How much video RAM do I need to run a 1680*1050 monitor?

post #1 of 11
Thread Starter 
Building new in January, looking to get a deal on a 512mb HD 4870. My 256mb x1950XT has served my 1280*1024 samsung very well, but the new build will have a 22" Asus.

So my question is... What's the largest resolution you can expect to be able to run on each RAM increment? 256, 512, 1gb, 2gb?

1GB seems most fitting. 512MB is a bit pushing it for that resolution.

512 is sufficient for that resolution. You can go wrong with 1gig though especially if you plan to upgrade your monitor later. The more memory is needed if you plan on playing at 1920x1200 and above with heavy aa and af, but imho 512 should be enough at 1680x1050.

I've played Crysis at 1920x1080 on my 9800GT with most setting maxed. No AA.

The gameplay was almost identical to that whilst running 1280x1024 - Perhaps a tad slower.

1GB Is ideal - But You'll be fine with 512. Especially on a 4870, which blows the 9800GT right out of the water.

Hope that helped.

I would say 1024MB min because games like GTA IV require the extra Vram

512MB is perfect for that resolution. Anything higher probably should get fed by 1GB+

512 is fine for 1680x1050, im running a 4870 and its perfectly smooth, 70+ fps on all games except crysis type games, with 4xaa on.

Crysis wants almost 700mb Vram memory at that resolution but most other games use less than 512. Newer games ARE going to use more than 512 at highest settings so I would go for a gtx 260 896mb/ 4870 1gb/ 4850 1gb. GTX 280 is overkill and a 9800gt wont take advantage of the 1gb the way a 4870 would.
