Just something to think about. 🙂

Back OT: The X2 will be released soon and so will the 8.8 Catalysts which have hopefully been optimized for the X2 with lots of XFire game profiles. Here's to hope. :beer:

Are you sure? Because for 2 4870s in CF 600w are recommended...and even that should be to much...

Edit... Upps, should have used glasses...2 x2s....

Essentially, yes; you are correct. But that's based on some unknowns and some "your machine factors." I'll elaborate:

1. X2 isn't out yet. We don't know what the initial price will be nor what the "normal price" will be once the initial price gouging dies down.

2. Related to #1, we don't know what the price of the regular 4870 will drop to (after MIRs, etc) once the X2 is out. It might turn out to be much more financially feasible to get two 4870s and XFire them.

3. But you may need to buy another PS to run two 4870s; you would need four, six-pin PCI-E connectors to do so, but you only need two PCI-E connectors (one 8, one 6-pin) for an X2.

4. Heat output of two HD4870s will be considerably more than a single X2; though most of it will be vented out of the rear of your case, it's still something to consider. Also taking up an additional 2 PCI slots.

Personally, I think the price of the regular 4870 will drop a decent amount, but the performance of the X2 will just be staggering. There's got to be a reason to shell out the extra coin for the dual-GPU card over buying two regular 4870s besides the "Look what I've got!" value.

Yes, it will...

Remove the drive cage from the bottom, and get yourself one of these to replace it: EX-33

This works great actually because it leaves you a nice big pocket of cool air from the front intake fan for your video card(s). I used to have my mid-tower Lian set up this way. The only drawback is that is makes replacing the motherboard a pain because the HDs stick pretty far out the back of the HD cage in the drive bays. That is ultimately the reason I went for a full E-ATX full tower (that, and the $50 price on the Lian-Li built Rocketfish case).

Yah, i'd take the r700 over CF 4870's just to say, "I have the fastest graphics card."😀
 
i bet FEAR looks incredible at 2560 x 1600 8xAA 16xAF 97 FPS.

they left off this:

Crysis: 640 x 480 2xAA 2xAF 23.77 FPS.

😉
 
@dennilfloss - that review link is for 3870x2.

@jaredpace - there are better reason to own R700 over CF 4870, but sure enough that's at the top of the list.
 
Playing on 30" with AAx4 or AA8x at 60+ FPS!!! :shocked: That is just sick sick sick :shocked:
