$2000 vista gaming system

First system build in roughly 10 years. Need cost/performance suggestions.
My goal is to run at 1920x1024 with out lagging badly. I would like to run dual monitors at some point but its not required. I play GuildWars and EQ2 but will be trying age of Conan.

I am looking for a case that I can work in easily with my big hands and a good monitor that will run the games I play . This is what I am thinking about at this point. Thank you in advance.

Geared towards upgrades every 6-12 months. Will be adding another drive for more storage later.

Well a few points to consider.
* DVD burner - get at least the "Retail" version, because it comes with the software to view/burn the DVD's for like $3-5 more.

* CPU HSF - go with:
Thermalright Ultra-120 CPU Cooling Heatsink - Retail
http://www.newegg.com/Product/Prod [...] 6835109125
and
Scythe S-FLEX SFF21D 120mm Case Fan - Retail
http://www.newegg.com/Product/Prod [...] 6835185004
for maximum air cooling. It'll cost about $80 or so with this combo, but will be the best and coolest setup right now.

* Case - I wouldn't spend $280 on a case, but that is me. I'd go with at least a Antec 900 or Cooler Master 690 case, which would save you $160 or more with one of those 2 cases. They are very good at cooling and are fairly roomy. They aren't full towers, so that might make a difference to you.

* PSU - I'd pick this PSU over the OCZ one you picked, for a couple of reasons. First, it has 52A on the 12V rail and has plenty of connectors. Secondly, it comes with a 5 yr. warranty and is cheaper than the one you selected, but will be able to SLI/Xfire easily if you need it to.

* GPU - I'd go with a 8800gts or 3870x2 for maximum gaming power. They are more $ right now, but are worth it, IMHO.

* Mobo - I wouldn't spend $250 for a mobo. You can do pretty much everything with a p35 based mobo and save about $100 or more with them. I'd look at the Gigabyte DS3R, Abit IP35, or the Asus P5k series of mobo's. They are priced around $130 or so.

The savings in the case and mobo will allow you to spend about $290 or more on the GPU, if you decide to do that. So if you combine the price of the 9600gt and the $290 you could easily afford a 3870x2 or probably even the 9800gtx that should be out soon. You can decide, but that is where I'd spend my $ at.

24" 3ms DVI Widescreen LCD Monitor ....1920x1024 with out lagging badly.........hmmmnnn ur 9600 isn't going to let you achieve that.

I think you mean 1920x1080 or 1920x1200. You may want to get this display 24" display for $319 http://www.newegg.com/Product/Prod [...] 6824211009
I would go Vista 64 with 4G of memory 8 would be better if your going to spend that kind of money on a motherboard
you should get an EVGA 780I http://www.newegg.com/Product/Prod [...] 6813188024 and for a case
go for one with plenty of room and air flow like the Thermaltake Armor or Armor+ http://www.newegg.com/Product/Prod [...] 6811133055, I would go with the 8800GTX because the prices are falling and they give you room for more power in the future http://www.newegg.com/Product/Prod [...] 6814130072 the Q6600 is a good processor but you may want to look at the E6850 http://www.newegg.com/Product/Prod [...] 819115028.

One correction. I have dropped the raptor for this:
Seagate Barracuda 7200.11 ST3500320AS 500GB 7200 RPM SATA 3.0Gb/s Hard Drive - OEM

Just forgot to update that list. Thank you again for the suggestion.

i second the suggestion for a single card setup. a 8800GTS will do nicely at 1920x1200 by itself. Also, SLI performance benefits vary from game to game, so you wouldn't really be getting a performance increase across the board. also, a single 8800GTS would cost less than 2 9600GTs.

The last two hardwares: case and M/B.I think it is better to change them to value products.then buy a 3870 X2 $450 instead of 9600.

me too... you could, if funds are tight, hold off on the X-Fi card...

I like the last build, it makes more sense and won't break the bank. The onboard sound these days are pretty good, so I'd hold off on buying it. If you feel the onboard sound isn't what you wan than go and get the audio card. This way you can save $85 initially and then see if you like the onboard sound. I use onboard sound and am quite happy with it. To each their own.
