If I was interested in breaking a bank account I would reccomend much different so far. Of what I have suggested, only the "most expensive DDR RAM" and the GeForce FX 5950 are expensive.
Every thing has a cost, but I could easily have gone overboard and reccomended a crap load of stuff that costs way more...
Take my new setup for example...
New Motherboard: 200$ (before tax, free shipping)
New Gig of RAM: 200$ (")
2x New Raptor SATA 10,000 WD drives: 270$ (")
New Power Supply: 80$ (before tax, 10$ shipping)
It's insane... but I sacrificed the video card (for a temp, though malarkeyTY, video card, FX 5200... which I knew sucked, but I had no idea it sucked this badly) for the Motheboard, hard drives and RAM costs. I figure in 3 months the 5950 should be easier priced. :-)
Anyway..
I reccomend you go with NVidia MSI cards. They will have the best visual rendering quality over all cards for sale, THOUGH, you will sacrafice some FPS unless you have at least a 5900 FX series card. I think it is worth it to have a better look myself, but I'm comming from a visual interest rather than just a game play speed interest. :-p
I reccomended Geil Golden for the reason that Particle posted. The ram I have now cost me about 200$ before tax when I got it, now it is at least 25$ less, not to mention I purchased a GB worth, when most people only really need 512 MB.
Also... make sure that you get Dual Channel ram! :-p
