Hello, so I have an old Win XP system lying about with a Core 2 Duo E6300 and 2 Gb of RAM but no graphics card, and I'm thinking about popping one in but I'm not sure what to get. Basically I want to know how high I can go without being too bottlenecked by the ancient CPU.

TIA

A reasonably quick C2D will still play some games fairly well. Not the latest shooters though. Up to HD 7770 (or NVidia equivalent, if there is one) would be a reasonable match for an E6300. I had my HD6850 paired with a dual core of that era and it was fairly well balanced between CPU and GPU on games like Crysis.

Highest you should go is maybe an HD 7750 since it only draws like 50 watts(not sure about GPUs that draw less) and sadly your CPU may still bottleneck it some. Also, make sure your PSU doesn't explode when you add the GPU.

Btw, what PSU do you have/what is it rated to provide in watts.

I actually have a Corsair CX430 that's not being used, so PSU isn't a problem.

7790 is too much. Actually a 7770 may be slightly bottlenecked, the E6300 is a fair bit slower than the dual core Athlon I had which was balanced with a 6850/7770 quite well.

So maybe the 7750 as jordan said.

I have actually the same configuration, #iceman500, Core 2 Duo E7500 2.93GHz running with ASUS P5KPL-AM/PS Mobo & 2GBx2 800MHz DDR2 RAMs with XFX Radeon HD 6850 1GB DDR5 using Corsair TX650, working like a charm, no problems running Battlefield 3, NFS The Run, COD MW3 with High Settings & V-Sync Off..
If you have Corsair CX430, you can get Sapphire/Asus/XFX 1GB DDR5 HD7770..

Yeah, absolute max would be a 7770
