you don't need an intel retention bracket for an AMD.

PC P & C 860w PSU is far more than you need for 2x 4850 in Crossfire.
Or were you planning on going for CrossfireX 4x 4850? That would be about the right PSU size for that.

Does it work well with AMD processors I just read the push pin system really sucks?

Yes, I am planning on running 4 cards in crossfire eventually right now just have to stick with 2 plus will see how the 4870's are price to performance but eventually I will need the extra power in the PSU.

only intel uses the pushpins.

what resolution are you running? you might be better with a single 4870

I don't see the need for the 4 cards in crossfire, you've already got a powerful and pretty energy efficient system. better ways to get more performance.

------------------------------ Intel qx9650 @3.81GHz (10x multi) + EVGA 780i SLI mobo @381MHz FSB
2x EVGA 8800GT 512mb OC'd, OCZ DDR2 1066MHz 4gb
OCZ 850W PSU, Seagate 750GB HDD SATA 32mb cache CM Stacker 830 SE
Sound setup: FireFace 800, JBL 4328 speakers

Well I agree 4 does seem like overkill I might just stick with two but keep the more powerful PSU anyway.


Oh ok I thought the push pins were for AMD too but glad to hear its not.

heres the general rule of thumb for added performance with added cards, if your talking games that scale up faily well. in some cases a single card outperforms multiple cards.

adding a second card boost performance by about 50%
adding a third boosts an additional 10-30% many games get little to no performance gain from the third.
adding a 4th boosts by less than 10% most games are not helped at all by the 4th.

Idealy youd see +100%, +50%, and +33% for the 4th. so you are far from getting your moneys worth with crossfire or SLI
