Upgrade Video card to..?

I want a video card capable of running games Like Team fortess 2 and left4dead without lag.



Here is what I have right now.

[Display]

Processor: AMD Athlon(tm) Processor LE-1640 (2712 MHz)

Operating System: Windows 7 Ultimate, 32-bit

DirectX version: 10.0

GPU processor: GeForce 6150SE nForce 430

Driver version: 181.72

Core clock: 425 MHz

Memory interface: 32-bit

Total available graphics memory: 831 MB

Dedicated video memory: 128 MB

System video memory: 0 MB

Shared system memory: 703 MB

Video BIOS version: 5.61.32.25.02

IRQ: 22

Bus: FPCI|||The Nvidia Geforce 9600 GT is an excellent video card for the money. For the games you suggested, it should easily be able to run them at high settings unless you have a 2560 x 1600 resolution monitor. [http://www.newegg.com/Product/Product.as…



If you are planning on running Crysis Warhead or the like, then i would go with an Ati Radeon 4850 [http://www.newegg.com/Product/Product.as… or an Nvidia Geforce 9800 GTX. However, these are LONG video cards. Make sure they fit inside our computer case.|||Anything that uses a PCIe 16x slot should work.



I'd recommend a ATI 4770 (~$99) or a 4850 (~$50 more, but if you find a good deal on it get one over the 4770)



If you want NVIDIA I'd suggest a GTX 260 Core 216 (~$150 after MIR)



You have an integrated Nvidia card but it doesn't matter which brand you get if you get a discrete card.
