Need some quick assistance please.

post #1 of 13
Thread Starter 
Since I sold my ati card I'v been using a 8800gts temporarily. Now for the first time I will be going with nvidia and SLI (minus the 8800gts). I'v recently been eyeing up the 460's and they have been proven to be very good in SLI and also price/performance wise is very good. Now heres comes the issue, I recently read a thread on here regarding how much to games actually use vram, my question is, is 2 768mb 460s going to cut it with the games that are out know at 1920x1080? or should I get 2 1gb 460s to SLI?

Which ever you choose please give reasons.

Thanks OCN

By the way its got be non-reference cards because they use g92 mounting holes. and I have spare mcw60 and an apogee gt cpu block that i'll mod

you must understand that 1.5 GB of VRAM is an enormous amount. Most don't require more than a gig and NONE require 1.5 GB. Furthermore you will be gaming at only 1080p, this is not by far the max resolution of these cards. Maxed out at 2560 x 1600 would show a pretty full VRAM reading but STILL not hit the limit in todays games. You're safe.

The Only Game you may have problems would be Metro 2033 that game requires more than 1 GB to perform properly, but if you can get two 460 SLI i would recommend MSI Twin frozr version 1 GB you will be able to play pretty much all of the games in high setting.

So Pull the Trigger.....

I guess 2 768mb at 1.5gb is what I'll be getting.

REMEMBER In some games in SLI you can not share the MEMORY you will only see 768mb.....

I do not believe that you will have 1.5mb of vram with two cards
if I remember correctly when you SLI two cards it does not double your available vram

also the 768 version has a narrow 192bit memory interface vs. the 256bit interface
of the 1 gig cards

I would go with the 1 gig. cards and never have to worry about the what if question

I was initially going to get the 1gb versions however thought maybe the 768mb will suffice. maybe I was wrong and it might be better to stick to my initial thought, as you said making it more future proof.

two cards with 768MB or RAM does not = 1536MB in total... it equals 768MB and two GPU's.


you better off buying a GTX560 instead of a multi-card set up.

Another option is to pick up a used ATI 5 series or GTX 470, these can be found for about the same price as two 460's and my 470 has yet to disappoint me
