SLI or new GPU?

[Szat]

Hey All, been a while since I last posted. Should I dual SLI by getting another 512mb 8800GT (preferably from PNY, but I guess the manufacturer can be different now?) or upgrade to a new GPU. My specs are in my sig. Keep in mind my PSU, I don't know how much more power it can dish out for a new GPU. I've used Newegg's PSU calculator and it cuts it close with a "new" GPU released a year+ ago.

I would upgrade to a single newer GPU...

ditto. Look at either the 460's from Nvidia, or anything from ATI in the 5770-5850 range.
