To SLI or not to SLI?

post #1 of 46
Thread Starter 
So I'm pretty good as far as what to look for in every component in my soon to be AMD build. But, a few quick questions.

Would it be dumb to get an SLI motherboard like a DFI, Abit, etc. (in other words, a good one). and just say, the card I've been looking at, the XFX 7600 GT XXX edition, which from what I understand is just an overclocked regular 7600GT. It's gotten some good reviews. Here's one. http://www.legitreviews.com/article/312/12/

The point would be to save a little money now, and upgrade in the future with another one of these cards and run in SLI mode.

I'm also thinking, why not just run the SLI now? My wallet ain't so happy about that.

Another quick question. The max, max, I want to spend on getting two videocards/PSU or just a single Video card is $400. If I ordered a computer right now, would it be wiser to go for one of the single more powerul cards, and save a little on the motherboard? Or just go for it and get 2 video cards and a PSU if needed for $400?

XFX GeForce 7800 GTX is about $410 dollars. I could get this, and have the option to get another one when my FPS start sagging with all the new games coming in 07 08 and 09.

the same site is offering, for 20 dollars less: Two (2) eVGA GeForce 6800 GS 256MB PCI Express SLI Video Cards and an Ultra X-Finity 500 Watt SLI-Ready Power Supply

AARRRGGHh!!!! seriously, the model numbering system for both ATI and Nvidia is rediculous. It's making this a headache! I'm in the market for a new system and I want to keep it ideally around $700 most, but I might splurge and spend $999 at the most. I'll be supplying my own optical drives, hard drives, keyboards, mice, monitors. Case/PSU, board, CPU, a 1-2 gigs of RAM, GPU. That's it....

Personally I think SLI is a bunch of crap, by the time you get ready to buy your second card there is a better one for the same price, skip the 2x7600GT altough they are really good and go with one 7900GT, thats plenty of gaming performance, youll save money and wont have to buy a SLI PSU which can be expensive, hope your getting a much better CPU

Yeah, the way I think, twice the price better equal twice the performance. With SLI, it doesn't.

What about getting some $400 nice card that could do SLI in the future? xfx7900gt is looking nice to me right now.

ok

only get SLI if you get a new mobo that supports 32 lanes (like the asus A8n32 SLI)

becuase if you dont each card will only use 8 lanes, shearing half the performance, BUT if you get a board with 32 lanes, you will see amazing boosts in performance because thay will use the full 16x for each

ok, Get a really nice mobo, sli or not, you will get more quality out of it. get the 7600gt, and get a really good psu. good psu's are a good investment. sli isnt crap that a unfair opinion. 2 7600gt's will not beat a 7900gt, and will generate more heat. But its a considerable booste to go from 1 7600gt to 2 7600gt's. and they are cheap but offer good performance.
EDIT: i agree though, no matter what get a board that can run full 16x on each pci e bus.

SLi is worthless in my opinion unless your running a 30" LCD, or have one of the cards already, its worth getting the better card for the price of the 2 lesser card for less than the 2 cards would be anyways and you dont see much of an increase

2 7600Gt do beat 1 7900GT, but the 7600 has some big disadvantages and of course 2x7900GT kill 7600GT SLI

Thats not true at all whatsoever. Even the 7900GTX doesn't really saturate 8 lanes. 2 16x lanes may actually be slower because of the two seperate chipsets supplying the lanes.

Which would warrant getting a great 16x2 board, and perhaps in the future, picking up another 7900gt if I'm starting to see some slower FPS.

I want something I can upgrade.
