Too much GPU for CPU?

I'm looking to upgrade my (very old) graphics card. I've got an older rig (Athlon 64 X2 5000+, 4GB RAM) and I want to know at which point have I purchased too much GPU for my CPU to handle. Is that possible? I'm thinking about the SAPPHIRE 100358L Radeon HD 7770 GHz Edition as that's about the maximum amount I would want to spend. And for the trolls and flamers, I did search the forums for a few minutes before asking.

Depends if you are going to buy a better cpu anyway than get something more serious like a 7850 or better otherwise 7750/70 will do.

It just means when you get round to upgrading your CPU you'll see an even bigger performance jump.

I did something similar with an older athlon 64x2 system I had a few months back. I installed a 7750 into it and whilst I did notice an improvement, I wasn't huge. So I ditched the cpu, got an i3 3rd gen mobo and ram bundle, with the 7750 and the change was immense. Hope that helps and good luck!
