Long winded answer time.
There is a one day special on the MSI 450 GTS. They're overclocked and cost $99 each.
They use one 6 pin (he has a Cooler Master PSU that cost $200+ and only has two PCIE) and eat 105w max draw. They're 1gb.
The 460 costs at least $130+ shipping. That's $260. He would then need to go out and replace his PSU which would cost well in excess of $150 for a good one. His Cooler Master has 5 19 amp rails.
The 450 (believe it or not) with a very mild overclock beat a single 470, make less noise, consume less power (a good 50w less I hasten to add) and kick the crap out of the 5850 he just sold for $200.
He is using a Core 2 Duo E8600 that we are not sure we can overclock yet. Thus, CPU *IS* going to be a bottleneck. My 470 gets 15k 3D marks. A 460 can beat it in Vantage with an I7. Bottleneck. My 5770s should have scored 17k+ in Vantage yet scored less than the 470.
At the price they are asking for a 450 here? oh noes, terrible. But, what people didn't think of was that they are pretty much on level peggings with a 9800GTX. Imagine them in SLI
So they are basically Nvidia's equiv to the 5770 and we all know how those perform in Crossfire.
Not only that but I think they're very pretty.
Mini lightning?
Then when you consider this.
Which is chuffing disgusting given that last week that card was $250 with an instant 10% off (so $225
) and that SLI 460 on his current pile of hardware is a no no? no brainer dude.

Take a look through that. Take the overclocked scores and I think you will be pleasantly surprised. They most always beat a 470 to a pulp and at times sniff the ass of the 480
