Found out my Lynx L22 is good to go for Win7. Still waiting to hear from the Samp folks. Sounds like you can tell Win7 to run in XP mode which, I guess, means that any apps that require XP will be OK.
I went ahead and ordered the new box this afternoon. It will be an Intel Core i5-760 CPU on an ASUS mobo. Win7 Pro 64-bit, 4G DDR3 1333 RAM, 1TB HDD, 1G Radeon HD 6850 video card. $1100 + shipping. That's a whole lot more computer for about $150 less than the old box I bought 7 yrs ago. Amazing.
I seriously thought about building it myself and I tried and tried to find the same (or better) parts but the best I could come up with was just under $1100 which did not include any tax, shipping or my time to put it together and pull my hair out if something didn't work....not to mention a warranty.
Anyway, glad to be started down the road to recovery.....
