So my GPU fried. Do I get GeForce or Radeon?

Currently using a Radeon 7770 VERY good good with a great price point i'd probably get the 7870 same card almost just a newer series of it with better performance. But if you can find good prices both are great brands. Go with whatever gives most bang for your buck.

Brand loyalty is stupid. You buy the card that performs (check benchmarks on reputable sites) best at your price range. It's that simple.

nvidia ftw .i had a radeon ( a cheap one but it was supporting a few games) , their drivers are a lot buggy and after the updates you might have to reinstall the drivers to make it work right.

You can still use PhysX with Radeon GFX cards you know... That's why I prefer them.

It's quite simple actually.

You go nVidia if you have the money, AMD if you don't.
All the clowns below me voting for AMD are just a bunch of cheapskates who probably buy B-brand food and watch B-movies.

get the Geforce GTX650 TI Boost ;)

Since the new console genration will have ATI GPU and AMD CPU i would prefer ATI, cuz many games are consolports and also ATI has a better price/performance ratio ;)

+Driver Probs were fixed long ago...

I'm always been with ATI/Radeon... usually they are better in the mid-segment so for 100-200 you're generally better of with a Radeon... Nvidia used to be superior in the high segment, but we are talking about $600-800 pieces of hardware.

Still, there are a lot of differences between card generations, manufacturers and so on, i'd check the actual comparison charts. Also, you might also get a slightly older, more powerful card rather than a newer mid-range one, as there are no compatibility issues nowadays (remember shader model 2.0/3.0 issues, years ago?)

DO NOT blindly go with any brand. Check reviews and find out which has the best price/performance ratio, which depends from where you are buying. As far as physX is concerned, do not take that as a deciding factor in which card to choose, since not many games use it.
