In reality it would be nice to be somewhat future proof. I never worry about being able to SLI cards like the 590 bcs I will never buy them. In all practicality all I really need it to do is run a single GTX 480. (Can you believe that a good friend just gave me the card??)
Listed below. Keep in mind that I prefer to spend as little as possible...
Should they be able to run any single card without worry? Honestly this will prob be my last graphics card upgrade on this machine since I'm running a q6600 with DDR2 RAM. After the 480 my CPU becomes a bottleneck. Unless I OC of course (to 3ghz at most).
Would it really be worth the $20 + for one of the other two that I listed above?
Well I like that you recommend the cheapest of the 3. Would you not worry that it's not SLI certified? Also, you don't think it would be worth it to pay the $15 extra for the thermaltake that has 100 extra watts and 9 extra amps?
First off the V2 is the newer more efficient version of the TX750.
SLI certified means nothing=companies have to pay for the label
Anything below Thermaltake's Toughpower XT series is of questionable quality.
