Would I be Bottlenecked - Page 2

You have to get the same type of card. It can't be 1.5GB and then a 3GB otherwise you'll only be able to use 1.5GB.

You won't notice it UNTIL YOU PLAY ON A 120HZ MONITOR. Then the bottleneck is CLEAR on ANY AMD chip at ANY speed. I witnessed this first hand on a 965 BE & a 1090t..... both were running at 4.2ghz and couldn't keep up with two GTX 460's, nor could it produce 120fps when the Sandy Bridge I sold before it kept it above 160fps 100% of the time. Good luck.

I would wait till Kepler is released. Heard rumors that it's going to be this year, not 2012 as thought. BD will be out too so you'll be able to do a huge component overhaul at once.

FYI. I bottleneck with two GTX 460s, and my 1090t is at 4.135ghz. You'll Defiantly bottleneck with two GTX 580s.

There will definitely be a bottleneck.

Will you notice it with today's games? Probably not.

Will you notice it with future games? Definitely.

My first gtx 580 is a palit 3GB.

Thanks for any responce
I agree with people saying it's bad idea to pair 1.5GB and 3GB cards. I'm thinking in best case scenario you will be throwing away perfectly good 1.5GB of ram on 1 card, in worst case - who knows what weird problems you can get because of that... I mean did anyone even attempt to do it in real life? I've never heard of it. Either save up for another 3GB card, or sell yours and get 2 matching 1.5GB.

Regarding bottleneck - short answer yes. Long answer: depends on the game. In GPU intensive games (Metro, Witcher 2 with ubersampling) your CPU should be enough, but in anything less visually demanding you will most definitely be bottlenecked.

A small bit of bottleneck, but really unnoticeable.
Sometimes it will, and your I7 will too. Here is my I7 @ 4.0Ghz severely bottlenecking my 580s in Crysis @ 1920x1080, DX10 maxed out with 16xAA. Crysis 1 is old, but still pretty graphically intensive.

580s in SLi aren't really meant for 1080p.

A properly clocked i7 isn't going to bottleneck any card(s) for it's "intended" resolution.

Well, you are on 1080p, aren't you? As well as OP, if his signature isn't outdated. So yeah, in some cases you both will be bottlenecked.

Never mind, I thought you were sloppyjoe123 since you quoted my post.

To answer your post: yes, and no. What is your definition of "inteded" resolution for 580 SLI? If its some guy to just play some games, then yes, 2 580 aren't needed. But what if I want to run my games maxed? I mean fully maxed, with decent level of AA? A single 580 won't do on 1080p. Or take me for example.. I like to run my games maxed out in 3D. But it's still 1080p. It's not that black and white. But generally yes, I agree.
