Max GPU for my system

[Rossington]

Hello peeps,

I have an oldish PC that wasn't too shabby when I first bought it, but now it's starting to struggle running even older games on Ultra. Witcher 2 being the game I'm playing through at the moment.

Basically, I'd just like to buy a new GFX card, but am wary that the rest of my setup might not have the oompf and end up bottlenecking a swanky new GPU.

So as per the title, could anyone tell me what the most powerful card I could get without it being bottlenecked?

What info would you need from me to be able to tell?

Cheers in advance for your help.

PS. I really am just looking for a quick and easy solution. Not really looking for advice on other components.

Okey dokey, I have -

PSU - Corsair CMPSU-850AX
MOBO - Gigabyte X58A-UD3R
CPU - Intel Core i7 930 @ 2.80GHZ
RAM - 12GBytes of DDR3

Current GPU is an AMD Radeon HD 7900 with 3072 MB.

I'm not too fussed about budget, as I just need to know the best I can get and then can work my way down from there if need be.

If you need any more info, let me know.

Well I wasn't expecting that! So good news!

One thing though, my CPU is actually overclocked to 2.8 already. Would that make a difference?
