SLI for me - GTX580 vs GTX580 3GB Phantom

post #1 of 12
Thread Starter 
Hello

I'm choosing between two dual card setups: A GTX580 SLI versus a GTX580 3GB SLI.

I play at 1920x1080, and I have no intention of going 3D or using multiple screens. Will 6GB of VRAM come in handy anyways, or will 3GB suffice?

I would consider the Lightning GTX580, but there is no full cover waterblock for it.

Cheers

The 3gb will be just fine for that resolution, no need for more if you arent going to have more monitors

2GB of VRAM would suffice at 1080p.

To be honest, in my opinion, SLI 580's is a waste on a single 1080p monitor. But if you have two, get two regular 580's. You won't benefit from the 3GB versions at that resolution at all.

Yup, I'll be getting two MSI GTX580 OCs. Stock board, affordable and compatible with the waterblock.

+1 for all of you. Many thanks

Wait xfire wait, dont be fooled, if you get the 3 gb 580 and you sli them you will not have 6 GB of vram, dont be fooled, the ram is always going to be the same. So if you sli 2x 1.5 GB 580, you will only have 1.5gb of vram for usage.

While this is true, it doesn't change anything, the 1.5 GB is more than sufficient for a single monitor.

3GB is A LOT. That would still be a lot for a 2500 resolution. I would save money and either SLI some 480's or 570's. That's just my opinion though. I'm cheap.

get the regular 1.5 GB version with custom quality cooler that will allow you to overclock high

PS: since you're going watercooling, just get any reference, or compatible boards with improved power system
