Hey, I am looking to upgrade my GPU as playing games on the lowest settings isn't fun anymore and with the newest games I could really use more FPS. I am currently using a GTS 250 that is like 4 years old, I was using two but sadly my motherboard died and needed a quick fix.
I was looking at buying one of these;
http://www.amazon.co.uk/Gigabyte-7950-Radeon-Graphics-Card/dp/B0071LP5ME/ref=sr_1_9?ie=UTF8&qid=1374596126&sr=8-9&keywords=amd+radeon#productDetails
or
http://www.amazon.co.uk/EVGA-660Ti-GDDR5-Graphics-Card/dp/B008YINJK8/ref=sr_1_22?s=computers&ie=UTF8&qid=1374596267&sr=1-22&keywords=nvidia

Current specs
CPU - intel core 2 extreme x9650 @3.00
MB - Gigabyte g41m
750W PW
Would it be worth upgrading the GPU? Would I see a good improvement with my current specs?
Thanks

EDIT: Sorry forgot to mention I play on a 27" screen @ 1920x1080
 
Solution
Neither, get a GTX 760. And yes, you would get a boost, but it'll bottleneck. This GPU should be life support until you come up with the 500$ to build a new rig.
