Thinking about adding a second 7800GT

[sep]

I've got a BFG 7800GT and was thinking of adding another one to get SLI performance. First, has anyone mixed this card with a diffrent brand? Second, do you think my Antec TrueBlue 480 will handle it?

Thanks,

Third... almost certainly not worth going SLI 7800GT's

I'd consider selling 7800GT (these seem to do well on eBay) and going for another better single card solution 😀

i.e. 7900GT if u want to OC with pen & new fan for 7900GTX speeds... if not then suppose you could go x1000series?

i would agree, its almost never g a good idea to go SLI on older cards just to improve performance. sell ur 7800 and then buy a newer faster single card. if ya have enough money left over THEN think about goin SLI/Crossfire. that will make ya more future proof than 2x7800gt's will.

*EDIT* OH by the way 😉 if u notice my sig i just HAPPEN to have a 7900gt for sale. already has all the mods and comes with a NV Silencer 5 rev 3.

I'd say to sell your 7800GT and pick up 2x7900GT's. Now THAT is a nice power increase. You can mix card brands, but they have to be exactly the same model. 7900GT + 7900GT, not, 7800GT + 7900GT. Your power supply should be sufficient if you have 20 AMPs or better on the 12V rail. If you have a voltmeter, you may want to check it out. Also check if your PSU was SLI approves. If it is, the manufacturer usually has a sticker on it saying so.
