Before buying a HD-7770, is my system fine?

[cyberpks]

Hi,

I am looking to buy a GPU for my system that is now a little old. Following is the configuration:

Processor: C2D E-4500 (OC'd at 2.7 Ghz)
PSU: Corsair VS-450
Mobo: MSI G41 P26
RAM: 4*4GB DDR3 Kingston 1333 Mhz
Monitor: AOC 22" Full HD

Ok, now I am looking to go for a GPU for some of my work that cannot be done on my Laptop, and as my Desktop - PC sits idle most of the times so I was looking for a simple upgrade.

I need to work on some 3D Modelling and Animation Task and some of Casual(+) gaming. I know that 3D part requires more OpenGL processing etc. and etc. and a Quadro would suit me more, but the Game part is also there and then a Low-end Quadro might cost somewhere around a Mid-Range Gaming GPU.

So, actually what I wanted to know is that I have a plan to get a Readon HD 7770 (Sapphire 1GB), or otherwise a 7750. But the thing that is causing confusion is that my CPU is quite old and I assume that it may cause a bottleneck for the GPU. Or should I go for a low-end 6670?

Please let me know, if something is not ok with that upgrade. And worth to mention, I am not is a mood to go for a new CPU right now .

I recently read an article dealing with the core 2 duo. http://www.anandtech.com/show/6670/dragging-core2duo-into-2013-time-for-an-upgrade The 7700 will do just fine with that cpu.
