Are you an idiot?
Oh please, by all means then tell us how much better a 5770 is over a 9800GTX+?
And explain to me the benefits of a 128 bit memory buss and 2 gig of memory over 512gig of memory and a 256bit wide bus?
Now, I'll grant the 5770 is not a bad card at all, well woth the money in its self.
But when it comes down to putting raw frame rates on the screen, it is neck and neck or only slightly better than a 9800GTX.
It is not worth the upgrade, you need to go on up the ladder a couple of tiers.
Idiot? Maybe. But I am sensible idiot who doesn't like to see people toss money for no good reason.
The 5770 is only 1 tier above the 9800GTX on the hierarchy chart.
It is a general rule that to "feel" like it was worth the upgrade, that you got your monies worth, you need to jump at least 2 teirs on upper end cards, and 3 tiers on lower end cards, or you simply won't notice a lot of difference.
