But if you aren't going to overclock then the Platinum is good as well.
I'd only go with the 2 Gig kits, 1 Gig just isn't cutting it any longer with modern games.
There's around 10 raptors between me, family and friends going on about a 4 year average. There has been none that have gone bad, and one DOA, an OEM from Newegg. Raptors are SATA as well. If your budget is tight, a good 250+gig 7200RPM drive will do fine, but the raptors are still the fastest magnetic SATA drives out there.
BTW, take your time getting this together, Bethesda has put out ANOTHER game full of bugs. Look at the forum to get an idea at the extent, I've actually lost interest in playing until a patch is out. The rat *******s!!
