Should I go SLI?

post #1 of 11
Thread Starter 
Alright, I've been considering getting another 8800gts 640mb but would spending the 350$ be justified? How much of an increase in performance will i be looking at (dx9 and dx10 games). Would another 8800gts in sli outperform a single gtx? Lets come together and help me make up my mind,

What is your native resolution and what games will you be playing? I think you should spend the money on a step-up to an 8800GTX and get a PC Power & Cooling 750-Silencer. This way you can do 8800GTX SLi if you need to.

I would only go SLi if you have a Native Resolution of 1920x1200 or higher. If you run games at 1440x900 or 1680x1050 I would just upgrade to a GTX.

Native resolution is 1680x1050 and I game at that resolution as well. My step-up expired (yea i know im a dumb ass for not using it). From what i understand SLI 8800gts 640mb are pretty damn amazing. but i wanted your guys' input. I intend to play Crysis and UT2007 when they are released but right now i play CNC3 and Stalker

I say no. You will have to buy a new PSU as well. The X-Connect will NOT be able to handle that.

I think that you will see better performance; espeically in DirectX 10 Games with the matured 8800/SLi Drivers. However, I think that you will be taxing your PSU a bit too much. If you want to get better performance I would get a least a 600W (700W idealy) Power Supply and another GTS. If you still want a faster computer I would get another 2GB of ram and overclock your CPU more.

About the power supply, Newegg has a deal on the OCZ GameXStream 700W Power Supply, it's only $120 after Mail-In Rebate.

I would get a PC Power & Cooling 750-Silencer over that OCZ, because customers and have been having some problems with OCZ.

A single powerful card (or processor core) is always a better choice because not everything supports SLI (or multi-threading). 640MB GTS SLI would be undoubtedly powerful but you wouldn't see a substantial benefit in some games, especially at those resolutions.

I don't know the exact performance gains from GTS SLI, but checking here might be a good place to start.

IMO, get a GTX and upgrade to SLI if you get a bigger screen.

I would go for it if you have the money, but I don't think your 550W can handle two GTSs so you might need to upgrade that as well.

Agreed. The best thing for you to do would be to get:

-eVGA e-GeForce 8800GTX Graphics Card
-PC Power & Cooling 750-Silencer Power Supply

It might be helpful to reference these charts from THG. Just check out the performance of a 8800gtx on the "VGA Charts 2007" and compare the FPS 8800gts 640mb sli setup on the "Dual & Quad VGA Charts 2007" chart. Could give you a good solid reading of what kind of performance gain you will see should you choose to go the glorious sli route.
