If you already have a 4650 then getting another for crossfire would be the best option.
The 5570 performs around a 4670, so it's not going to be much of a step-up.

If you want game then don't get anything lower than a 5750, it's always better to save up a bit more and get something that will last. Going cheap on the GPU will cause you to upgrade sooner than later.

Prices should come down a bit once the 460 is released, 2 weeks won't hurt =)

Yeah, I am just trying to get a feel for what cards I should keep my eye on.
Since my purchase date is so far away prices will most certainly come down.
and then i will be able to reassess my options.

I suggest go ahead with crossfire in the end plus you will able to use more than just two monitors. In crossfire the 4650 will smoke and thing less than a 5670 or a 5750.

Yea but then when its time to upgrade he will have to sell/get rid of both those GPU's. X-Fire 4650's is weak for Crysis, produces more heat than needed and will not work with a few titles.

I would say wait and get a 5750/5770, you will have DX11/low power draw/low heat/no CF issues etc...

Here is a review based on the 4650 :

So its on par with the 4850 give or take, I would rather have a single 4850 than dual 4650's in CF ;)

Wow, I thought the performance gain was only like 50%
Will the performance gain still be there if the crossfire is only at X8?

The penalty of 8x crossfire/sli is fairly small while gains are depending on the title and drivers. 40-60% in games that scale fairly well while games that don't scale at all like GTA IV will be zero since it doesn't use more than one gpu due to rendering is mostly cpu which sucks ass no matter what platform you play on. Performance increases more when overclocking is factored in. Performance can increase 5-10% right away when only one of the cards is nuked and the other is at default. Note clock synch no longer applies to Nvidia sli and ATI crossfire unlike the old days of 3DFX. Performance can jump 10-20% + when both cards are maxed out on top what you will get at defaults.
