Advise for video card.

I have a 2 1/2 yrs old evga 8800gts 640mb is it worth it to change it to this? http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4369731&CatId=3775Was thinking of getting another 8800gts 640 for SLI but they don't seem to sell the 640mb model anymore.

My 8800gts still works fine but thought if its much better was due for an upgrade. ALso have the option of waiting awhile till the gtx 275 are cheaper.

hd 58xx series launches tomorrow

hd 5850 (on par with gtx 295)

hd 5870 (on par with asus mars)

hd 5850x2 (no equivalent but assumed sli gtx 285 (three way))

hd 5870x2 (assumed to be equivalent of tri sli gtx 295)

No don't replace it, it's not bad at all.
