I want to upgrade my GPU, my current PC is an HP P7-1234 and my friends have said that my CPU will bottleneck me. I was interested in a GTX 650 or 660 and was recommended a 7750. If you recommend a card, please tell me how much watts are required, thanks!

Your 300w PSU is what limits you more than the CPU. That is why the HD7750 recommendation makes sense (and would be a good overall choice anyway). To go with a stronger GPU (which requires more power), you would need to upgrade your PSU as well.

I have no problem upgrading my PSU as well, with that said any recommendations?

I would say a HD 6670 if u don't want to waste your IGP (Depends on your CPU, A6-36XX/A8-3850/A8-3870K's IGP is like a HD 6570 according to the performance and can work together with HD 6670), or HD 7750 (If u don't mind or has only A4 CPU), which has a 55w TDP and no need for a 6-pin power conductor which your PSU may doesn't have.

For GTX 650 (TDP 64W but still need a 6-pin power conductor)or 660 (TDP 140W) u should change your PSU and I'm afraid that your CPU may bottleneck these two cards.

Will it be worth it after the bottleneck do you think? How badly will it be bottlrnecked (GTX cards).

Which specific CPU is in your HP? Also, what is your total GPU and PSU budget?

I would never pair a weak CPU with a strong GPU. (or sCPU with wGPU) It's a waste of money and in some CPU-demanding games (says FC3 and the coming GTA V), you'll see (E.g, GTX 660 can achieve 30fps in high settings in X game but could only reach 70%-80% fps pairing with a weak CPU and that's the optimistic imo)

Thank you so much for these answers. Can you recommend me a good motherboard and processor for next gen gaming that I could use with higher end GPU's?



Don't...

Sorry for bumping posts stuff...

But could u give the budget what u would like to update with, 'cause there is no limitation unless there is a money limit.
