MSI NX7600GS-TD512Z

Bought one of these about 6 months ago and it's the best Gfx card I've ever had. I used Half-Life 2 to benchmark this card, and it's absolutely fantastic. No slow-down whatsoever and everything was turned on, and it never struggled once. My PC was a Core 2 Duo 2 Ghz with 2GB RAM. I was gutted when my mainboard died. The new one I bought only takes PCIE cards so I now have this baby sat on my desk :(

To summarise, they're well worth the money. Don't think twice about buying one...
