What is a good video card for high end PC games?

I don't need anything fancy and i'm not looking to spend much. I'm looking for a nVidia GeForce. I have found a few so far.

MSI N9500GT-MD1G-OC/D2 GeForce 9500 GT 1GB 128-bit GDDR2 PCI Express 2.0 x16 HDCP

--

MSI N9400GT-MD1G GeForce 9400 GT 1GB 128-bit GDDR2 PCI Express 2.0 x16 HDCP

The motherboard I have is a nForce6M-A. I have 4g of ddr2 ram with a 3.2ghz dual core processor.

Are these good video card to get or are there better?|||The 9500GT and 9400GT are low end cards. You'll want an 8800GT/9800GT (75-100$) at the very least. You could also go with 9800GTX+/GTS 250 (125-150$) or GTX 260 (175-200$). The best of the best is the GTX 295 at over 500$.|||I think the obvious answer is whatever your money can buy. In this case the GT9500, but I believe there are better ones now.|||I believe you should save up and buy a 8800GTX+.

If U want a better card get the Geforce GTX 260 core 216 or higher.|||look for 1 gig anything with 2.0 x 16 will be new and better umm you might wana look for ddr3 it will br nicer and go for an EVGE anything over or around 200 bucks on newegg.com
