I am not tring to be funny , but i've read some of your post , and I think it's time to get a new board that has a Intel chipset Nivida chipsets don't play well with SSDs. If you are not ready to go with a I core 7 sys there still plenty of the DX48BT2 775 boards out there New about $220. reman. $150. Thats the way I went because I had tooo much 775 stuff around .
+1. The nvidia 680i chipset series caused me nothing but grief and I haven't gone back to nvidia since. There are plenty of 775 mobo’s out at good prices.
For reference, I have used Crucial's 256gb C300 on an Nvidia 790i Ultra using a pcie x 16 host adapter and got great performance.
