The RPM only is the speed the HD spins at, but depending on the data density of the HD, the HD transfer speed can be higher even if the HD is 5400 RPM compared to 7200 RPM. Raptors are expensive and the Caviar Black can have simular performance with a cheaper price and more capacity. You can get a 1TB WD Caviar Black for $94.99 over at Newegg which costs alot less than the Vaptor, just you game will load a few seconds slower, thats all. Don't bother with the WD Caviar Blue, it's slower and have less warranty. The Caviar Black have the same warranty as Raptor, so you don't have to worry.

Don't bother with the Seagate Barracuda drives... they have quality control issues over their firmware issues... Even though it's fixed, you shouldn't really trust them unless you using a Seagate drive just to backup data.

Also, a midrange card is pointless anyways when high end ones can be bought for $20-50 bucks more (e.g. 48xx series on Radeon and 98xx or GTX 2xx series for Geforce) and won't handle demanding games like Crysis if you are planning to play games at high settings in DirectX 10. If your concern is FPS and/or overclocking, you most likely won't need two graphics cards with SLI or Crossfire. You also don't need to have to get a video card with HDMI... you can also hook up a DVI to HDMI cable to get the same benefit, except no audio.

Also, without a motherboard, like said earlier, you don't have a computer... so it's best to find the best one first and never skimp on motherboards...
