Having ignored my PC for so long, since I got my PB, I've decided that beefing up my WinBox system might not be a bad idea. And maybe turning it into a low-end Gaming/Media center PC. So here are the specs [Bought in 2002]: 2.4Ghz Pentium-4 (Northwood?), 512RAM, Dual HD (80GB 5400 main, 200GB 7200 slave). Windowz XP home. One thing I forgot to mention... The video card: RADEON 7500 64MB PCI Yeah, I know, PCI graphics, but this thing doesn't even have an AGP slot . So my question is, what is the best graphics card I can put on this thing? Is it even worth it? Any suggestions? Currently, I can play the Sims 2 at 800x600 at full speed, dipping only when there's a lot going on (1024x768 runs pretty well too), and watch 720p WMV at full framerate. Halo also plays well. Is there anything I can do to make this PC into anything remotely considered a "Gaming PC" [Low-end of course], or is this as good as PCI graphics will get? Another question, where can I buy more RAM for this thing? Speed is 2100, and I can't find it at retail stores anymore. Thanks in advance.
