I currently have an "Intel 82915G/GV/910GL Express Chipset Family" integrated chip that is fairly decent for having come with a new Dell. It is a 128 MB size memory. But I now have got games that this chipset cannot handle without the frames freezing or other stuff. So, I need a new card that can run Half-Life 2, Counter Strike: Source, America's Army, and Doom 3 with the textures tuned to at least Normal graphics. All this time I've been having to tune textures, etc., down to it's lowest in order for gameplay to be smooth, but even still my card runs slower than hay on certain scenarios or levels that demand big cards even when they're turned as low as can go. So what card can I get that would run all these games without problems? Money is somewhat of an issue though, I can really only afford to spend about $150-$180, so I was hoping eBay would have to do, even though it's quite risky. Also, I want a card with at least 256 MB Memory, that will fit inside my Dell Dimension 4700. Any suggestions as to a card that won't make me go broke?
