I[COLOR=black] stated in an earlier thread that my FX-60 tanked and I had just bought a new VGA so I decided to RMA the card and put together a new rig. Here is the hardware I have ordered(most of which I have not received yet):[/COLOR] [COLOR=black]Case - Thermaltake Armor (w/25cm side fan)[/COLOR] [COLOR=black]Motherboard - EVGA nForce 590 SLI [/COLOR] [COLOR=black]CPU - Athlon64 X2 6000+[/COLOR] [COLOR=black]CPU Cooler - Thermaltake V1[/COLOR] [COLOR=black]RAM - OCZ PC2-6400 "nVidia SLI" 4GB[/COLOR] [COLOR=black]VGA - EVGA 8800GTS SUPERCLOCKED 320MB[/COLOR] [COLOR=black]I'll be using some of my existing hardware such as my HDD's (1x Hitachi 80GB SATA, 2x WD Raptors 150GB ea), opticals (Plextor DVD+/-RW & Plextor CDRW), PSU (Hiper Type R Modular 580W) and maybe my sound card (Creative X-Fi Fatal1ty).[/COLOR] [COLOR=black]I plan on adding another VGA in the near future and since I have always been an AGPer up to this point I have no experience with SLI or any multi GPU platform for that matter. So I guess my Question is this:[/COLOR] [COLOR=darkred]DO THE GRAPHICS CARDS HAVE TO BE EXACTLY THE SAME (make, model, clock) IN ORDER TO USE THEM IN AN SLI CONFIGURATION???[/COLOR]
[COLOR=black]I have read conflicting information on the internet about this subject which is why I am asking here. A lot of you guys know your stuff. Any details and whys on this subject would be greatly appreciated.[/COLOR]
I should point out that when I say "near future" I mean I'm just waiting for all my hardware to get here so I can put it together, then I will begin parting out my older stuff on eBay and use the profits from the sales to buy another VGA. Sorry for the double post, too late to edit.

Sorry to go OT, but I can't resist. Your AMD went out, so you bought another? That'd be enough for me to lose faith in a brand if their $1,000 processor was no good.

If I do recall correctly, if they are both SLI-capable, but different models, then they will perform at the speed of the lower card.
Good to see a fellow Louisville resident in here...go Cards! My FX-60 tanked because my 11yo daughter (who thinks she is technically inclined) decided she was going to OC it to 4Ghz per core. She maxed out the voltage...miraculously the MB survived. The one thing I can smack myself for is not setting a password on the BIOS (which I now have). Thanks for the tip Homer. I have read that in an article somewhere, but I have also read elsewhere that they both have to be exactly the same. Like I said, conflicting info.

With SLI they only need to be the same chipset. ie, 2 x 7800gt or 2 x 8800gts. If you you have one with more or less ram than the other then it will default to the same as the lower card. The same thing applies to Clock speeds too, if you have one GPU at 600 for axample and another at 500 they would both run at 500.
Just bear in mind that if you want 2 x 8800 you will need juice, 150w a piece plus the rest of your setup will take a lot of power.

They used to need to be exactly the same cards when it first came out, but nvidia have since updated drivers etc.. and now they just need to be the same model.
eg 2x 6800 GT's 2x 7800's
you get the idea I'm sure. Still can't figure out why you would really want to mix and match though if you're putting both in at the same time.
Well you never know. I bought the EVGA 8800GTS Superclocked 320MB version which EVGA claims is a limited edition release. I plan on buying another exactly like it, but with the advent of the 8900 series on the horizon and the Radeon 2900 series release tomorrow, they might disappear from the market a month from now. Thanks for the solid info fellas(mates), not to mention the link Undies - very helpful.

I used a wattage calculator totaling up the power usage of my entire system. It said I'm going to need 650W minimum if I want to add another VGA. I prefer modular. Any suggestions?

I would have thought any of the more modern enermax or tagan or decent make will be up to the job. Not modular but something like this should do it. OCZ GameXStream 700w Silent SLI Ready ATX2 Power Supply
