i have a alienware Intel Core2 Quad Q6700 2.66GHz 8MB Cache 1066MHz FSB Alienware 750 Watt Multi-GPU 2GB Dual Channel DDR2 SDRAM at 800MHz - 2 x 1024MB evga NVIDIA nForce 680i SLI Motherboard 250GB SATA 3Gb/s 7,200RPM 16MB Cache vista home premium im running 2 xfx geforce 8800GTS 320mb XXX IN SLI and i cannot run crysis on high detail just medium this cannot be possible there is got to be something wrong i use only 1 of these card and same medium only i though with SLI would be much better, as i saw in the charts, what can possibly be wrong?crysis has lastest patch 1.2 and video card as well thanks

I heard the 320mb gts is not a good card so maybe thats why...

Agreed! I have seen many people run into problems with the 320mb and below cards. The game simply takes more memory GPU memory.

Best,

what resolution are you running? the 320 starts to choke when you get to 1600x1200 i think...

also know that SLI is only around a 25-30% performance increase

so if it lags with 1 card, when you do sli, it will have 25-30% less lag

If you want to play Crysis at max settings you need a lot more than 2x 8800GTS 320M cards in SLI. Refer to the following article in which 3-way SLI with 8800 Ultras is needed for max settings in Crysis. It will be another year or two before we see single cards that can display Crysis in all its glory. And by then the current crop of games will look just as good if not better than Crysis.

System needs:

More ram
Better GPU

Not REALLY sure why a such a system would come crippled with 2Gb and a GTS320?

Get 4Gb ram and an 8800GT should give u a smile.

320 is not a bad card (the Crysis demo ran fine on mine at 1680x1050 with a mixture of medium and high settings), but from the research I've done 320 SLI is just not worth it.

Sorry - I hate to give bad news.

320MB of Vram for crysis, don't expect much. The GPU is a bit weak compared to the G92 8800GT.

I don't know what settings you're running on, but it's more than likely your 320MB of memory will not cut it. Sorry that Alienware tricked you into buying two weak cards.

Why not put one powerful graphics card (8800GTX) in your system instead of two weak cards in SLI, Crysis does not scale the best using SLI, it never did from the beginning. I remember a review where two 8800GTS 640's (G80) couldn't really perform much better than one 8800GTX. Its always a good idea to buy the best single graphics card solution. That 320MB is really limiting you in most newer games that are texture & shader intensive. You never told us what resolution you are running, seems like you never researched anything before buying and now your paying for that mistake.

I can run all high with a few non-essential things at very high with AAx2 at 1680x1280 (second number maybe wrong I can't remeber first one is right)"

these are the important parts

You left out the number one most important part, the power supply. Its responsible for stability and reliability as well as component life. Ripple current will kill your components over time and many underestimate the importance of UPS (uninterrupted power supply).

As you have been told, 320MB isn't enough for Crysis on high nor the best match for SLI. I researched that ahead of time and decided against buying a second 8800GTS 320MB.

Anyway, look at this link below. Notice the 320MB GTS keeps up with the 640MB GTS on medium, but falls way behind on high.

One more link: Notice not only does the 320MB GTS fall apart in crysis, but the 256MB 8800GT tanks even worse.
