I speak as a massive fan of Classic Who, and of Nu-Who. As much as I dislike those terms - it's all Doctor Who. No doubt, no evidence to prove otherwise.
I have to agree with Reece, (and I'm pretty sure that fellow Whovian Shelaf can back us up).
I love all of the Doctors, even including Paul McGann who has done some incredible Audio episodes. But seriously - I am a massive believer that it was the Eighth Doctor who fought in the Time War, as the last novel to feature him was essentially a prelude to the Time War. Whether you consider Classic Who novels as canon is completely different.
You may not like Nu-Who, but it's like Star Trek: Enterprise. You may not like it, but there's indisputable proof that it's canon. ("These are the Voyages", your milage may vary extremely on that one, but it gives irrefutable proof that TNG and Enterprise are in the same universe.)
Same with Nu-Who. Primarily over the Series 4 Specials and Series 5, we've been greeted to images and references to the previous Doctors, such as William Hartnell, Patrick Troughton, and of course, earlier between Series 3 and 4, we had Time Crash, the meeting between the 5th and 10th Doctors, and Sarah Jane Smith is practically a living embodiment of a reference.
Let's not forget that there have been ton of references to Classic Who throughout Nu-Who and of course, the Sarah Jane Adventures.
But enough of that, time to debunk.
In the real Doctor Who, the TARDIS is powered by the "Eye of Harmony" a core of a blackhole created by Omega and kept on Gallifrey under the panopticon on Gallifrey. Not a dimensional rift;
Ahh, but the TARDIS only needs to "refuel" at the Dimensional Rift. The Eye of Harmony may have been destroyed during the time war, or is time-locked. After all, it was created by the Time Lords.
In the real Doctor Who, the TARDIS has two set's of doors, the outer plasmic shell door, in this case the 1950's London Police Telephone Call Box and the inner doors. The Real World Interface is the name given to the inner doors connected to the outer;
Fairly sure this is a cosmetic issue that the Doctor decided to rectify. Also, you know, special effects technology improvement and all that. Technically this is one of the things that may have been borrowed from the Cushing films in the 60s.
The inner sanctum of the TARDIS, the main control room, always consists of white hexagonal walls with pale yellow roundels evenly space and inset;
Take a look at the 7th/8th Doctor's control room.
Not so white, really. And not to mention much larger than the original main control room sets, which did vary quite a bit through the run.
The control console is the same as the internal architecture of the TARDIS, which is dimensionally transcendental and is also dimensionally 'grown' not constructed. The internal architecture is controlled by the TARDIS main computer and can be rearranged and redesigned and renewed by the TARDIS main computer. The TARDIS therefore does not need any primitive mechanisms added such as a bike pump;
Clocks, desk lamps, a compass... who's to say the 9th Doctor didn't add the Bicycle pump. The 8th seems pretty happy to add those things.
Other attributes to the real TARDIS is a cricket pitch, medical bay, library, pool, sauna, cloister room, several thousand quarters, wardrobe and power room (housing the Artron Energy Converter). Of course this is to cater to the Doctor's whim, other TARDISes can be programmed with different architecture;
This has also been referenced in the new series, as Reece said. And also, the Doctor designed Amy and Rory's quarters as a bunk-bed, and I'm fairly sure the sick-bay has been mentioned recently.
Gallifrey is well protected and connot even be penetrated by a TARDIS. The main protection is that the entire Kasterborous system is within a state known as "zero time". But as a back up, the entire planet - not just the capitol - is protected by a Transduction Barrier, a powerful force field that absorbs all forms of energy whether it be electromagnetic, gravitational, strong nuclear, weak nuclear, kinetic energy, mechanical energy, chemical energy, or dark energy etcetera. The Transduction Barrier Generators translate the energies and forces collected by the shields, converts it to usable energy and translate that back in to the barrier. Therefore GALLIFREY still exists and always will;
It does still exist, like Reece said. Just time-locked. But please, read up on the Etra-Prime Incident, which proves that there are ways for the Daleks to breach those barriers.
Also, it's worth nothing that the Doctor sealed Gallifrey's fate himself with The Moment, a heavily modified De-Mat gun, removing everything in the Time War from conventional existence, presumably at the cost of his 8th incarnation's life.
The Cybermen were originally from the planet Mondas, the sister world of Earth (not parallel Earth), but further ahead in the evolutionary scale. They were originally biological, but at some point in their history moved from biological to the synthetic in a technological singularity. Building huge Transmat Engines, the Mondasians could move their entire planet from star system to star system in the blink of an eye. Cybermen were vulnerable to gold, as gold does not oxidise and therefore could cause damage to their artificial respiratory system, literally causing them to suffocate.
The Mondasian Cybermen were referenced back in 2005's "Dalek". The Parallel Cybermen are referenced as exactly that. They have the same motivations as the original Cybermen, and only require the brain.
However, as of 2010's "The Pandorica Opens", the Mondasian Cybermen continue to exist, as proven by the fact that the Damaged Cyberman present contains a decayed human head in its helmet.
Regarding the gold? There hasn't been a situation to test that yet.

Once again, I am a fan of both eras, but to label one as Real and the other as Alternate...
Seriously, dismissing the continuation as an alternate reality, and shouting that the Classics are real, just because you don't like it, is just as bad as someone saying "I don't like it cuz David Tennant ain't the Doctor anymore. Matt smith suks lol."
I'm sorry but this is one of my absolute pet hates. Quite frankly, if it wasn't for Russell T Davies, Christopher Eccleston, David Tennant, (A massive childhood Doctor Who obsessive I might add), Steven Moffat and Matt Smith, the Classic series would be rotting in the archive rooms. Before RTD came along, it was considered old news. Now, it has gathered an entirely new fan base - millions of new fans worldwide.
The nation's appreciation of it has plateaued at an all-time high. In the 80s, DW was being curbstomped by Coronation Street in the ratings, and was generally seen as crap. (Even though Sylvester McCoy had some brilliant stories.) Now, Coronation Street is the one being thumped, and DW is winning awards every single year.
The New Doctor Who is Canon.
The New Doctor Who is what made DW popular again.
(And hell, Andrew Garfield and Carey Mulligan's careers skyrocketed after their appearances.)
And quite frankly, it defies logic that the BBC would start planning a 50th Anniversary celebration if it wasn't entirely canon.
Once again, you don't have to like it, but you should see that it's the real deal.
It's ALL REAL Doctor Who. From 1963, right here to 2012. And long may it continue.
