OK I know this is Macrumors ( I was gonna say MACrumors but I didn't want to get flamed hehe) anyways. I have a pc it's a Dell Inspiron 2400 (eek!) 2.6ghz celeron 512 memory 80 gig 7200rpm HD. and INTEGRATED graphics. My question is. I would love to play Rollercoaster Tycoon 3 http://www.atari.com/rollercoastertycoon/us/gameinfo i have the game but it's unbearable. I believe upgrading the video card will improve it a lot. i was looking on newegg.com for a PCI videocard under $150 if possible. Has to be pci, no agp slot. Also i know a big bottleneck is the processor/bus. That can be upgraded i believe by putting a pentium processor in. but mainly i'm asking you guys to help me determine the best preforming video card for under $150. I found a Geforce 5200 with 256mb vram for like 90 bucks and also a radeon 9250. any imput would be greatly appreciated and i apologize for the long long post.
