Gang,

I'm building a new system.. I wanted to get an opinion my build.. and some recommendations before I purchase the rest of the system; This past weekend I found a great deal on a i7-950 for $199.00, if it wasn't a deal it seemed like a steal to me.. lol

I plan to buy these components

Asus Rampage Formula III "I'm sold on this one over the Extreme III"
OCZ SSD 60g (O/S Boot Drive) "Please recommend better if this is not good"
6GB 1333 memory 3x2 "Should I get more, or faster 1600 and 2000 is cheap, but I heard I wouldn't see a speed increase
Power supply "not picked, but i heard a 750watt was good enough?"
I want to go ATI Cross fire, with 2 cards but I'm not sure which ones to choose.

Any suggestions is appreciated..

Hey,

For the PSU 750w is good -- get a high quality brand like Antec, Corsair, Seasonic, etc. You could go lower (depending on the GPU you get) but for a high end build like this you probably want some overkill and safety for overclocking etc.

The ATI crossfire is basically only dependent on how much you want to spend. Toms will have a best GPUs for the money article on the front page. Get the best you can afford, because the GPU is more important than the processor.

Well the GPU should be = to the CPU. So a 950 cpu would be paired with a 5870 but you can do fine with a 5850 in crossfire. PSU get a Corsair 750W or higher. Iam not sure about the GPU due to not know what games you play.

2x 6850s in crossfire beat 2x 5870s in crossfire, 2x hd 6870s in crossfire will eat 2x 5870s in crossfire as the 5870s scale horribly in crossfire compared to the new hd 6xxx series (yes i know the 6870 is the replacement for the 5770 in their lineup as ATI changed the naming scheme)

1x hd 5870s is better than 1x hd 6870, but 2x hd 6870s beat 2x hd5870s, get 2x hd 6870s....... but just one thing can you wait? with sandy bridge around the corner and the rest of the hd 6xxx series and gtx 5xx series its worth the wait

SLI vs CrossFire: Which Dual-Card Setup is the Best?
http://www.maximumpc.com/article/features/sli_vs_crossfire_which_dual-card_setup_best

The Bottom Line

AMD has invested substantial time and resources improving CrossFire X, but it’s clear that Nvidia’s SLI is currently the superior dual GPU solution. Nvidia’s generation of DX11 cards scale very well when adding the second card, and SLI still works with more titles than CrossFire X, thought that gap is narrowing.

One thing that’s quite evident from all our testing: the Radeon HD 5830 is very much an odd duck. It’s been our experience that both single card HD 5830s and 5830s running in CrossFire X mode just don’t have the horsepower to justify its current cost point.

On the other hand, there might be times you might want to consider paired Radeon HD 5850s or 5870s, particularly if power, heat and noise issues are of concern. However, both the GTX 470 and 480 in SLI seriously spank AMD’s best in sheer performance.

In many ways, the 460 GTX impresses us more. Running in SLI mode, these cards scale well, never seem to get particularly loud or too hot, and can either stay close in terms of performance to AMDs high end card. They can certainly outperform the HD 5850 in most cases. And if you’re looking at Nvidia specific features, like PhysX or 3D Vision, the GTX 460 are affordable, even if you buy a pair. We’d strongly suggest stepping up to the 1GB version, however.

So are dual GPUs worth the cost and hassle? If you’re a serious gamer with 1080p displays or better, the answer is definitely “yes.” But take a look at what you plan on running, your resolution and other factors before you drop in that second card.

that review is old..... its not talking about the ATI 6xxx series.... we all know that the ATI 5xxx series crossfire scaling is rubbish

and the gtx 580 is not a very big hit is it? nvidia just rectified its fermi fail... the gtx 580 has similar performance to a gtx 480 it just draws less power and isnt as hot, theres nothing mind boggling about the gtx 580, im waiting for the hd 6950, hd 6970 and hd 6990 to come out

My last gaming rig had a Nvida 6800, but then I bought a Alienware gaming laptop about 2 yrs, ago with ATI's in crossfire.. and fell in love with them.. now you got me thinking I should go back to Nvida...

To many darn choices... lol

I like the ATI's because of the Eyefinity solution.. I know Nvida can do the same, but it doesn't seem as nice, any thoughts?

Malmental,

The problem is with Nvidia I would need to buy all HD montors @ $250x3, two Cards @ $250x2 and the 3d Vision @ $250, just to play the game across 3 monitors, even if I dont want 3d, those prices are kinda steep... lol.. with ATI all i need is 3 or 6 monitors and only 2 cards.. and I'm good to go, I'm not looking for 3d, I just want to span my games across 3 - 6 monitors..

the new ATI cards crossfire scaling is incredible "Check out Guru3Ds review. The 6850 is only 1 FPS behind a GTX 470 SLI setup at 1920 x 1200 in Metro 2033. This is the case in most other games too (6850 CF barely behind a 470 SLI). So I'd say go for the 6850 CF. I'm sure OC vs OC, the 6850s are still going to be considerably faster than 460 SLI. Most games are scaling at 90%+, it's absolutely crazy."

"CF hd 6850s are a flat out win over SLI gtx 460s"

told you crossfire scaling is amazing with the hd 6xxx series cards like i said go for 2 hd 6870s and it will be amazing
