7900GTO or 7950GT?
 

Since my current GFX can't quite handle the games anymore I've been looking into getting a new one - the problem is, I don't really know too much about it, so I'm hoping for some advise here.
I can pick between the GeForce 7900GTO or the 7950GT, according to the tests I've found the GTO seems to outperform the 7950, however, that is the 256mb 7950GT and the one I'm looking at is 512mb, so... help?

I have an XFX 7950 GT which performs incredibly well. It has gotten a 5290 in 3DMark06 and always has framerates above 60 in games like WoW, Battlefield 2 and so on. For future use it also supports HDCP should you ever decide to get HD-DVD and Blu-Ray movies and use a LCD with a DVI connection. It probably just comes down to price though, most flavors of the 7900GT/GTO
(GTX even) and 7950GT's difference in performance comes down to less than 10 fps under most circumstances, but I'd recommend the 7950GT for the bang for the buck.

I'm running a 512MB eVGA 7950GT. Athlon 64 X2 4800+, 1GB RAM (another gig on the way, but that's besides the point). There's not a single game on the market I can't max out at 1600x1200 - Oblivion, FEAR, Doom 3, you name it. Quake 4, I need another gig of RAM to have Ultra Textures be truly usable, but the GFX card isn't the issue there.

Have you checked out the XFX 7950GT? It has no fan, because (apparently) it doesn't need one! I hope that's true because mine maxes out at 80 degrees C when it's under heavy processing loads.

As I thought, the comparisons I've been reading about the 256mb version doesn't seem to do the 512mb justice - Especially if you're able to max out all those games Arainach. I think I'll try looking at a 7950, thanks both for your input.
I just looked at the XFX card, it seems to have some sort of "ultimate cooling technology" - I've just never heard of XFX before, is it generally a good brand?

Mine works quite well, it does however max out at 80+ degrees celcius. I don't know if that's too high (nVidia control panel says it's not dangerously overheating until it hits 130 (!) degrees celcius). If you do use the XFX cards, give it plenty of clearance from other wires and devices.
