I'd look at the TomsHardware CPU charts.....seems the Thermalright IFX-14 is the king of the hill right now.
Everything else looks pretty evenly matched as far as state of the art goes except for the old WD HD's. I'd opt for a single 750 GB Seagate 7200.11 before I'd do two WD's. About the same price too but you get an extra 110 GB with the one Seagate. I'd be willing to bet that the single Barracuda would be faster in gaming even if the WD's were in RAID 0.

If you opt for a 1TB model, I'd grab the Samsung F1 as the hi density 330 GB platters in this drive are even faster than the 7200.11 But not all F1's have the hi density platters.....It would seem only the 320 GB, 640 MB and 1 TB models have the hi density platters as the math don't work with the 500 and 750 GB models.
As I posted in another thread, the three most recent WD HD's in storagereview.com's reliability survey had the 3 WD models "more reliable than 4%, 5% and 12% of all other drives in the survey". That means 96%, 95% and 88% of other drives were more reliable.
