whats the point of having two graphic cards working at the same time? I heard some games you have turn one of them off. Hp Pavillion a1010n Asus P4GV-LA Motherboard Intel Celeron 2.93 GHz 160 Gb Hard Drive 512 pc3200 Mb of Ram 64 Mb Graphics Chip Windows Xp Home Edition

The point is having some games run faster, and less slowdowns during games, video editing etc. My Rig: 1040Mhz Pentium 3 OC'd at 1.2Ghz Aopen MX3WPRO-E mobo Intel 810 chipset Onboard Graphics Not sure how many MB 128mb RAM 120GB Maxtor Hard Drive My Old Rig: AMD K6 400Mhz

"whats the point of having two graphic cards working at the same time?" so the video card & motherboard manufacturer's can make more money...lol ASUS A7N8X-X Athlon XP 1800+ 8.5 x 200MHz 1024MB PC3200 2.5-3-3-7 Asus A9550GE/TD 128MB WinME/WinXP Pro SP2

That and it is important to remember that apart from games there is NO value!!!! You can avoid many of these Windows problems with Linux. Linspire eases the transition for new users

Two graphic cards allows for dual monitors.

Dual monitors are also possible with on modern graphic card as all newer ones have at least two connectors! The point of SLI is that you can get up to about 40% more power out of two cards than one. I've seen some of those tests where some older not supported games had quite a bit loss in fps performance but as they had been older a normal 6800GT usually had a very high fps rate and even with the loss in SLI mode it was still way above the lever where you get unstable movements. If you really need that amount of graphic power is something you need to decide for yourself. Unless you're a really enthusiastic play the answer surely is NO but if you are it's might be a YES! A nice option about SLI is that you might be able to upgrade the system with the same card later. But sadly you need exactly the same build of the card with the same graphic bios on it. The bios you can flash but getting exactly the same version of that card might get a little tricky! I have the A8N-SLI Deluxe myself but not because of the SLI but because of the build in S-ATA Raid5 controller. But the idea of being able to add another 6600GT later to boost up my graphic power sometime in the future is a nice one. If it ever happens I don't know because it's as likely that I will get an even faster single card for not much more then!

I have 2 cards and 4 monitors :)
