PC "restoring" with GPU change

[Dunkan77]

Hello guys,
I will get a new GPU to replace my AMD Radeon HD 7770 2GB ASUS and we have another pc that never got the hardware it deserved. This other one has a Core 2 Duo E4600 @2.4Ghz and currently a Nvidia GT 220 ASUS.
Will this quite old CPU bottleneck the Radeon? Please tell me as my little brother wants a computer for him and adding this card would make it a lot more pleasant to play on with the added GPU power. Only question is will it be bottlenecked?
PS: I also have a 450W PSU in there so its enough as the CPU is frugal on power
Thanks for answering guys

An AMD Radeon HD 7770 probably will be bottlenecked by the Core 2 Duo E4600, but that doesn't mean you won't get a substantial performance increase from the GT 220. A partially bottlenecked AMD Radeon HD 7770 is still much better than a GT 220.
