Hey guys.

Just have a quick flick through the different games benched in this review: http://www.xbitlabs.com/articles/video/display/geforce8-roundup_9.html#sect1

Now all I wanted to ask was, why is it popular opinion that if you are gaming on a 20"/22" monitor (1680x1050) then a 320mb gts would do just as well as a 640mb one, but if you jump up to a 24" monitor (1920x1200) then you would definitely see major improvements in performance by getting the 640mb gts? That above article seems to suggest that there is almost no difference whatsoever and therefore you will always be better opting for the cheaper 320mb model.

Using OCUK as an example, what then justifies the extra £52.88 you would pay to get the cheapest 640mb gts over the cheapest 320mb gts? Clearly I'm missing something or? :confused:
 
Im with you, i use tomshardwares VGA charts which also suggests that the difference between the 320 and 640 are minimal even at higher resolutions. I started a thread yesterday asking about an 8800 GTS 320 for a casual gamer and a lot of people were saying the 640 is better, which it most likely is, but not £50 better.

I appreciate all the help i get on these boards, and everyones opinion's, and it spurs me to research the issues that are brought up. But i wouldnt advise you to get the 640MB version at the moment.
 
Numbers do not say everything.

Although the FPS could look similar, the game could still "lag" due to more caching going on all the time.

IMO best to listen to people who have had BOTH of the cards - there are many such users on this forum.
 
OK I can agree with you there, maybe some people who have had the pleasure of using both cards could chime in with the differences they've noticed (if any)?

What you're saying about caching seems to make sense but surely any effect from it would show up in the minimum fps figures quoted in the charts?

I guess it's wrong to implicitly trust the one site since another one I frequent has a review from back when the 320mb 8800gts was first released and the difference is quite stark in a number of games.

Could the drivers really have been tweaked so heavily that the difference between the two models has shrunk with time?
