I'm going to get a new PC, since my old one is starting to show it's age. I already have an HD5850, but the rest of the parts are going to be replaced. My question is if I should get another HD5850 and use it in CF with my old card? Is a 750W corsair PSU enough if I chose CF?
I'm going to get a Phenom II x6 1100T.
Well, I've been using intel for a long time, and I like the price/performance of the newer AMD chips. Also I'd like to get a sandy bridge system, but it seems like there won't be coming any motherboards out with the fixed chipset before next month or so. Would you recommend an I5/I7? Price is important, I'm a student
That's fair enough, with gaming you never need anything more than a quad core though. So if you want to go with AMD, go with a BE Phenom II. I understand where you're coming from in terms of finances too, i was there at one point lol.
In terms of performance and OC-ability, nothing trumps Intel to be honest, but AMD provide some really good budget based builds.
Saying that, even Nehalem based builds (original I5) will still be incredibly potent today. The I5 760 costs around $200, couple that with a decent enough motherboard from Gigabyte or Asus and you'll soon be on your way to a decently OC'd CPU driving those two 5850's.
I won't go on any more about the actual rig itself, but OT i'd say your PSU will be able to handle two 5850's fine.
I'm not too sure to be honest, i'd honestly say you are well set with the 5850's. Unless of course you want to sell your existing 5850 and purchase a 6950 / 6970. Newer generation card, double memory, single GPU solution so no crossfire hassle.
On the Nvidia side, a GTX 560 or 570 would also be a good choice.
