Hmmm... I have two GTX 460s in SLI. They're separated by about 2(?) expansion slots, so they aren't directly touching each other. They run about 2c separate from one another, but my case has some decent air flow venting the heat.

Playing The Witcher 2 with both GPUs hitting 90%+, I'm hitting around 62-64c at about 50-60% fans peed (can't remember the exact digits). It's pretty hot in California right now too, so I don't think that's too bad. If you're super worried, just buy one of those Antec Spot Coolers and have it sit in the horizontal path of the two GPUs. If your side panel has a fan slot, you can forgo that completely.

Yes, im looking into that case that was posted earlier. I may get it soon.

Yes, but my motherboard has 3 PCI-e 2.0 slots, but only the two right together are useable. The bottom one is unfortuantly only one slot wide so a card wouldnt fit in there.

on my daughters pc i was able to cut a 200mm hole on top in front of the psu and i turned the rear fan into a intake so the front and rear fans intake and the top 200mm fan exhausts remember heat rises,thats the hard way or just buy a better case probably find a good deal like a 100$ thats the easy way

For your situation, the main concern for cooling a pair of EVGA GTX460 768MB SC is, IMHO, not that they will sit too close to each other (because your motherboard (MSI P55-G80) has one empty slot between the 2 cards.

The main concern should be the fact that the 2 cards use internal heat dumping design, exhausting about ½ of the heat inside the case. If this heat dump is not managed well, it will be recirculated back into the cards and might go through the CPU heatsink fan as well. Obviously, this is not desirable.
Additionally, the cards dump this heat via the front. So, you do not want a strong case front intake fan as its air current will run against the hot air exhaust.

For a low cost case upgrade, I suggest CM Elite 370/371 Black. These 2 cases have 2 side panel fan openings as well as 2 case top fan openings. With such features, you can setup a 'top-exhaust' solution (ie removing all those heat dump via the case top extracting fans).

CM 370/371 for US$50 + $17 shipping
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119241
If your budget is higher, consider the CM 690 II. Even the basic version (US$80 + $12) is fairly good already.
http://www.newegg.com/Product/Product.aspx?Item=N82E16811119215

For a PSU upgrade, your current Logisys might have enough wattage but it lacks 2 more native 6-pin PCIe connectors. You might try to convert two 4-pin Molex to one 6-pin PCIe connector but I would rather suggest you to upgrade to a PSU with four such native connectors (eg Corsair HX650 for US$100 after MIR: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012)

Yes, thank you. The first case is more in my price range and has alot more fan openings than I currently do. Thanks for the help.
