Need new video card now....for future upgrade?

Okay so about 1.5-2 years ago (I think), I built the following system:

EVGA 8800 Ultra Nividia vid card
Gigabyte p35-DSR3 Mobo
4gigs of Crucial Ballistix Ram
2 x 7200rpm Seagate 250g HD's
OCZ GameXsteam 700 Watt PSU
Lg 24" LCD Display
(etc..)

Well just 2 days ago my vid card left a suicide note on the keyboard and i found it hanging by a rope in the closet... Sooooo I'm in need a new video card. Well that would be easy, except in about 4-5 months I am planning on upgrading my system again (Not sure what I will do with the above items I no longer will use.. most likely >>>>> Ebay).

With that being said, I need a video card NOW as in this week, that either a) Will be goood-to-go for the next 1-2 years or b) that i can SLI/Crossfire within the coming months with another card when its time to upgrade.

I'm not a particular fanboy of either Nvidia or ATI as i have had both in the past and for the most part been happy with whatever i've purchased. My price range right now is less than $250.00

So I am asking for some suggestions for a video card that meets that following requirements:

1- Less than $250.00 (online)
2- Just as good performance if not better than my 8800 Ultra 768mb (which i looooveeeeeddd!!!)
3- Must either be an affordable SLI/Crossfire option within 4-5 months
OR
4- Must be a card that will run well for the next 1-2 years on the latest games
5- Must be 1g+ in memory
6 -Must run 1920x1200 on high to MAX settings smoothly. 10000x AA isnt necessary but I do like my games clean.

Lastly, my computer does 2 things: Plays games and checks my email(web browsing)...I dont watch movies, I dont burn dvds, I dont post Youtube, etc...Okay im exaggerating a bit, but the rig is about 99% games and 1% everything else, so i strictly need a gaming video card.

Thanks in advance for any suggestions
