I am at a crossroads guys/gals. 4 Year old system, started with a cheapie FX5200 lol, to an X850 and 1.5ish years ago in a discussion here Lasereth pointed me towards an X1950 which I got cheap ($60 after selling other card and rebates etc) and this rig has held me happy ever since. Bought Fallout 3 which runs suprisingly well at 1280x1024, medium quality, and then I bought Red Alert 3 and chop chop chop 15 FPS we go, until I dumb down the quality to make it look like red alert 2 ha! It appears that the new lines from nVidia and AMD aren't going to make the jump to AGP, so the best I can expect is to jump into a comfortable X3850, which is 2 generations newer for a sliver over $100.
Is it fruitless to spend the $100 to hold me over for another year and a half (crosses fingers) or is it time to bite it and replace M/B, RAM, CPU, Video. Any and all input is appreciated

Current rig in more details below. Thanks all!
