Ah one was IDE you mean? Sorry about that, though, IDE drives can still run on new computers
Its just not advisable these days.
My DVD drive is running in IDE though, since I forgot to get a SATA one!
The 8800GTS 640MB is fine for Vista, don't worry.
Well yeah, thats alright... but if you were going to avoid DDR3 in the first place, there are better boards out there now.
For instance, the Abit IP-35 Pro is amazing.
There is also the new X38 motherboards that may just be up your street
