Hey guys, Ill be making a computer rig real soon and i need some advice on the parts to select.

Im looking into the Nvidia GTX 580 and the new Radeon HD 6970. I know they are not the same level but they are the flagship single gpu cards on the market.

So my question is: What are the benefits of having an AMD cpu with a Radeon graphics cards, specifically AMD 1090t + Radeon HD 6970 vs 1090t + GTX 580

More about : amd cpu radeon

the main advantage is that AMD cards can be crossfired on an AMD motherboard, and NVidia cards cannot.

That's it.

thats it? no extra boost in performance or anything? wow

Well ive been looking at different setups and here are the cpu and gpu variants that i considered:

1. i7 950 + GTX 580 (+$220)
2. i7 950 + Radeon 6970 (+$70)
3. 1090t + GTX 580 (+150)
4. 1090t + Radeon 6970 (base)

The main reason why i havent picked up a 950 580 solution is because of the price. And since the 1090t is similar in performance to the more expensive 950, i decided to resort to the the cheaper AMD (Was this a good choice?)

Is the GTX 580s 150USD price hike a good deal for its performance? or would you rather pocket the 150usd and settle for the 6970 (Which is still amazing!)


I love performance, i love radeon, but i love performance. I want to see the justification of buying a GTX 580 over the radeon 6970.

Please help!

here's what I'd suggest:

the 1090t ($230)
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

AS Rock 870 Extreme 3 ($95) (which has 16x for single or 8x/8x Crossfire PCIe16 lanes). the 8x/8x loses only 2% (usually 1-2 FPS total) over a 16x/16x thats $40 more!
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

and 2x HD 6850 ($360) - 179.99 each.
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

You'll get performance exceeding the 580, the 6 cores of the 1090, and spend less than the 6970.

thanks for the suggestion! but i really want the 6970...dual cards are nice but i prefer one card solutions.

Also concerning mobos...is higher price usually better or is lower prices more suitable for gaming?

sure. It may be a bit overkill. You probably don't need *5* PCIe16 slots!

an AS Rock 870 Extreme 3 will work just as well with 2 PCIe16 slots (16x or 8x/8x)

lol yeah i thought about pcl slots overkill...

so there should be no performance difference between those parts right?

no but you can SLI them, they do make SLI AM3 motherboards..


However, all of the SLI-capable AMD motherboards are older technology, and they don't include newer features like USB 3.0 or SATA 6.0 Gb/s.

and in another 3-4 months (assuming the March/April release holds), they'll be even farther behind, as there won't be an nvidia board for Bulldozer

whoa whoa! I thought AMD cpus didnt support SLI...so is nvidia SLI performed by the mobo and not the cpu?

Correct. It's communication between the two cards, there's no reason for the CPU to have anything to do with it.

dang...i was just blown away. I always read how AMD chips cant run nvidia in SLI...dang.

So this bulldozer cpu (Researched it a little bit) seems like a bada++ cpu. Will the top of the line bulldozer cpu be like the 1090t right now? Similarly priced?
cuz i like the price of the 1090t right now and i dont know if ill be willing to let down a hundred dollars for a top of the line bulldozer

So what im saying is....are the bulldozer cpus meant to replace the phenom2's or watever including their pricepoints?
