Upgrade help :(

[entmutigen]

Well currently I own a Dell XPS 600, I have 4 gigs of ram, a P4 D 3.0 processor, Vista 64 bit.
Well thats just some specs I'm sure anyone can google basic specs

However I'm really confused, I own a 7900gtx and think it's about time to upgrade. I mainly multibox with WoW. So I have 2 screens 20" running at 1680x1080. I can get okay fps sometimes maybe one box at 30fps and the other box around 22fps. Well of course if I single screen it I usally run at max with WoW which is suppose to be at 63fps.
I'm on a budget at around no more then 400 bucks which is ruff I guess If that nice tax incentive comes I could afford more ( thank ya Mr. Bush)

So lemme get down to it, Would it just make more since to buy another 7900gtx and run it in SLI? I mean i would spend no more then 200 bucks.
I mean would it really help my game play to get two 8800gts and run sli, or even get an Ultra?
WoW is really the only game I play on my pc but mulitboxing seems to bring me down to a crawl.

I'm sorry if it seems I'm going on and on just very unsure and don't want to leave to much out. Really any advice would help, just did not want to get another 7900gtx and regret it.

Sell your 7900GTX and get a 3870 or an 8800GT. you simply don't need anything more for WoW. Welcome to the boards

evga has an 8800gt 512 on newegg for 240 shipped. That's about the best deal I've seen on either an 8800gt or 3870 from a reputable source, and it's too close to a 3870 to recommend one of those atm.

Thanks for the fast replies and the welcome! So I guess if I sold my 7900, then it would be smart to get 2 8800gt and sli? Would one card be able to handle the multibox with my two toons running around, that seems to be my main problem now? If sli does it require a bridge, or is it just plug it in and turn on sli?
