New system time!

[LgFriess]

Well it's finally time for a new desktop. It'll be a 99% gaming machine. I like to play everything... WoW to Crysis and anything else that I can find the time to get into.

Trying to stick around $1500 (a few hundred either way wouldn't kill me). I tend to try to get about 3-4 years out of a system with a video card upgrade here and there.

I know the latest/greatest video cards (true successor to the 8800gtx) are right around the corner so I'm going to just go with a single 8800gt for now, with hopes of just popping it out and adding one or two of the g200 series when they hit in a few months.

A few questions too;
1. Quad 9300 or the E8400. Am I killing the "future proof" thing by going dual core? Will I want to kill myself in 2 months when a slew of games hit the market that support quad? I plan on overclocking but just a little.

2. 64 bit and 4mb RAM or 32 bit and 2mb? I'm leaning towards the 4mb, 64bit Vista again with an eye towards the future.

3. 780i motherboard... overkill? I don't want to go cheap on a MB but I don't want to just throw money away either.

4. I've configured this thing with a soundcard. Will this give me a gain in framerates and is the sound quality that much improved?

I configured this thing mainly off cyberpower's site and THINK it looks pretty good. Please let me know if I'm screwing up too badly OR just waisting money on anything. Would you add anything that would make a world of difference for not a lot more money?

-CoolerMaster Cosmos S Gaming Full Tower

-4GB PC6400 DDR2/800 (Corsair)
-GeForce 8800GT EVGA brand
-X-Fi XtremeGamer

-Thermaltake DuOrb CPU Cooling Fan
-800 Watt PSU by Xion SuperNova

Thanks for your help!!

Update - ordered... changes were,
-E8400 (Plan on a very mild overclock, and will drop in a quad when games really use them)
-GeForce 9800GX2 (can sell it to a friend to make up a portion of the cost when the g200's hit... I admit there's nothing really smart about getting this card now, but what the heck. I game on a 24" and with a little overclocking it'll be fun to play with)
-ASUS 750i (780i seemed more then I would ever use... triple SLI? Not for me)
-Ultra X3 800watts PSU (better rep, gives me some wiggle room for future upgrades)
