Thank you so much. I had it in my head that the 250 was longer physically, and took more power. Both are backward and the 250 gts comes out as well as the 9800gtx in both. (a tiny bit better)
I also thought the 250 was much more expensive, but that's about equal as well.
I think I'll take your advice right down the line and get the gts250 and the e7400 as well. I already have 4 gigs of 800 RAM that I'm hoping I can keep.
