that's a bold faced lie, either that or it's ignorance. Crysis is almost completely GPU bound. I get the roughly same FPS with my c2d at 2.13Ghz as I do at 3.6GHz, it's indistinguishable.

pretty much any dual core CPU does alright in crysis and his opteron 175 is a dual core CPU... just as much as my old opteron 165 was.

AMD side the IMC for DDR1 is propbably a bit better than for DDR2 since there's little performance gained under AM2 than over 939...

intel side the system bus kind of criples memory IO performance anyway so it's not THAT big of a deal. Single channel DDR2 is not a deal breaker, atleast not in all things, yes performance takes a noticeable hit but it's not devastating and I'd assume dual channel DDR1 outperforms single channel DDR2 in more or less all regards.

In terms of DDR3, yes it is very expensive but IMO if you are building a new rig then i would recommend getting a DDR3 motherboard as you will use it sooner or later, but using the 8800GT's should give you at least a 100% performance increase if not 200%, hope all goes well with this build
guess you haven't seen any CPU scaling benchmarks for crysis which show dual to quad core scaling to be in the neighborhood of 1%

atleast in realworld scenarios. I'm sure that if you're using the sandbox editor and you setup a few thousand explosive barrels and you set them off simultaneously it'd scale better but that doesn't seem too significant

and here is the best resource
http://google.com/

here and now you DON'T buy a highend CPU for gaming, you buy it for everything BUT gaming.
anyone telling you to upgrade your CPU for this game should NOT be listened to. Maybe if you were looking at supreme commander it might be more justifiable, be even then it's not an epic leap. c2d is roughly 20% faster per clock. it clocks roughly 10-20% higher than k8(depending on the age of the core of course) under air. yes that's as high as 50% in some cases. but quite frankly if you've got a solid ~3Ghz k8 system there is no reason for an upgrade if your sole interest is gaming and you aren't made of money

Decivox, when running 2 video cards (SLI) on the DFI LANParty NF4 ULTRA-D, they will default to 8x 8x bandwidth(page 68 of the manual). The smarter approach would be to install the two cards on a Asus A8N32-SLI Delux board. Those would run at 16x 16x.

Like xlink suggested, if you already have a strong K8 system, just stay with it

Good luck

It depends on the resolution and settings that you are playing at. Most of the newer game engines such as the Crysis engine is almost fully GPU bound when played at higher settings. If you play at 1280*1024 with at least high settings than you will be 100% GPU bound with your current processor.

x8/x8 probably still wouldn't cause any issues with the PCIe bandwidth, I don't believe that the GT at full tilt would be restricted by the lessened bandwidth at all since it doesn't really come close to need the x16.

RPIJG, are there any reviews out there that compare the 8x/8x bandwidth and the 16x/16x bandwidth? I'm sure there is, I just haven't come across a recent one comparing any of the new video cards. By the way thanks for your post...interesting

I'm not sure if there are any as most mobo's only allow two PCIe states x1 and whatever is Max.

I suppose someone could try a single card at x4 and see if there was any difference, I know I asked someone about that with my P5K Deluxe and they were pretty confident that the x4 bandwidth wouldn't impair a 2x3870 crossfire configuration.

try dfistreet,someone on there did some checking as to the difference between x8 and x16 and so far there is no difference as the current crop of cards is not getting close to the max bandwith of x8 nevermind using x16 fully

RPIJG, I did do a test on my DFI at 4x and 16x using 3DMark06. The difference was interesting. At 4x I got a 8777 marks and at 16x I got 9693 marks. I'm kind of curious though what the results would be like with SLI at 8x/8x and 16x/16x.

perhaps 4x is too low, but I doubt that 8x will have that same effect. Perhaps in the bridged method there is some manner of bandwidth balancing? I don't know exactly what kind of information gets passed across the bridge.
