How much of a performace difference should I see from this new video card?

I currently have an integrated Intel GMA 950 128mb video card



I wanna get an EVGA Geforce GTS 250 1gb



What will the difference be in performance?|||Day and night difference



The GTS 250 is actually GeForce 9800GTX+, I have this card and its absolutely wonderful, only games that I cannot run full is Crysis and Far Cry 2. Crysis run at High, and Far Cry 2 tune 1 step down from max for certain setting. All other game such as FEAR 2, Unreal 3, Rainbow 6, runs amazingly



While the GMA is not for gaming at all. Its as fast as an asmahtic ants after a heavy shopping



Its the difference between can play games at good quality, and cannot play at all, heh|||If its a laptop im going to say you can not add a video card. If its a desk top you better make sure you have a PCI-E and if its 1.0 or 2.0 v. You will also need a 500w+ power supply.If everything is right you see a HUGH performance boost off the video card.|||little bit|||Going from integrated video to a GTX 250 is a HUGE boost- you'll see over 6X faster framerates in demanding games. As the previous poster has already mentioned, this is only possible on desktops.|||There will be a huge difference.
