Okay guys, I bought my first PC game (other than MS Flight Sim, and it is Half Life 2, with Counter Strike: Source. Counter Strike Source seems to be an awesome shooter game, rescuing hostages etc..and I love it so far.. Anyway, I have a Dell Dimension 4700 2.8 ghz Pentium 4 1.5 Gb Memory.. and a Radeon X300/550 video card that was the "upgrade" card that I paid extra for when I ordered the PC. The games run great in 800 X 600, but a little jerky in 1024 X 768, which has a better picture.. I want to upgrade my video card...so I can run in the higher quality settings. Also, I tried MS Flight Sim X, and I cannot play it on my PC, it is way too jerky, but I heard X was so graphics intensive, it would only play well on 1% of the systems out there.. I looked on ATI's website, and I see them as high as $800!!!! I'd like to ask opinions on the best video card that will work with my system, in the "less than $150" range.. I like the ATI products, as I've had good luck with mine in the 2 yrs I've had it.. There are a lot of things I don't know, such as whether my card is AGP?.. PCI??? Can someone help me make a decision on a good performing ATI Video card that fits in my budget?
