When you absoutely, positively, must have the fastest video card on the block, Asus has designed a monstrosity just for you.
The ASUS Mars 295 Limited Edition is quite the unique beast, rocking a pair of GTX 285 chips that are viewed by Windows as a GeForce GTX 295. All told, you're looking at 240 shader processors, a 512-bit GDDR3 memory interface, 32 total memory chips and 4 GIGS of RAM.
It's probably safe to assume this puppy is going to set you back more than a few bucks when it hits the shelves later this year, but if you're even entertaining the notion of buying a 4 gig video card that looks like a spaceship, money is probably not a concern. [TechPowerUp]
