Hi,I have a Soltek SL-75DRV4 P1 VIA KT266A Socket A MB with a Athlon XP AX1700DMT3C. I was hoping to upgrade the processor. The docs say max speed is 2100+. What I neglected to notice was that it wasn't the max speed that is the problem, but apparently the MB can't support Thoroughbred. So, not knowing this, I went out and purchased a Thoroughbred 2100+. So now I'm stuck. I can sell the TBred and buy a Palomino 2100+. Or I can toss the MB and get a new one. My purpose is to build a cheap system that runs FS9 ok.As a comparison, for my purposes, I am happy with my Dell D800 laptop with a 1.7MHz Pentium M, 64MB nVidia 4200Go graphics, and 1GB mem.So, in looking at Pricewatch and Tom's Hardware, it looks like the best bang for buck in my performance/price range is a Thoroughbred B 2.083 MHz 2600+ Socket A. Anything faster is 35-50% more expensive it seems. But I can't figure out what the specs for the MB are to use for this chip. I'm hoping the whole thing will cost $100 or less (MB and CPU and fan/cooling system), absolutely no more than $150.So, where do I go to figure out what specs for MB's are for various CPU's, ie what chipsets, speed specs, etc.?Second, can anybody help me understand why a Thoroughbred chip won't work on my MB (it does on rev P4 and above, just not on my MB's rev)?Thanks,Thomas

Ok, after some study at THF, it looks like I'm looking for an nVidia nForce2 (Ultra?) 333 FSB MB. Any suggestions?Thanks,Thomas
