This may have already been posted at some point, so, if it has I firstly apologize and would also like a link to the thread.

My question is just as the title suggests. Does a 1GB overclocked card perform better than a 2GB straight card? This is assuming that both cards are the same type just different memory values. I would like to know so when I build my next system I can get the better bang for my buck. They are GTX 550 ti if knowing what cards helps determine the answer.

As I said, it depends on the card. If you have a high end card like GTX 680, 1 GB vs 2 GB will feel a lot. However, if you have something like GTX 550 Ti, you will never tell a difference.

i doubt it will perform better but seeing how a card like the 550ti will most likley not be used in a situation where more than 1GB of vram is used, i can't say there will be a benefit to getting a 2GB card.

While that is probably true my question was mainly directed at whether a 1gb overclocked has better performance than a 2gb straight.

I could be wrong, but I don't see how more RAM will make a video card any faster.

Maybe if you had insufficient RAM, and that resulted in delays for texture loads (and be clear that I don't know the specifics of what happens when you lack enough video RAM to keep all needed textures loaded.)

However, would you say an overclocked 1gb would out-perform a 2gb regular. I think people are misunderstanding the question so perhaps I didn't phrase it the correct way. And maybe the fact that I included the example cards might be throwing people off as well.

Ok, just so we're a little clearer on the topic; all I'm wanting to know is if there is really a difference in performance with 1gb overclocked vs 2gb regular. And also with the cards I listed as examples if anyone would happen to know if one out-performs the other.

Now from what I have noticed from self-research is a difference in voltages, an overclocked having a higher frequency than the larger memory version that is not overclocked. So does that mean it is going to perform better or is the larger memory amount going to out-perform simply because it has double the memory?

My intuition is telling me that the 1gb overclocked is going to be slightly higher in performance than the regular, non-overclocked, 2gb card. If it helps to know specific values then I will list them below.

1GB = 950Mhz core clock, 1900Mhz shader clock, 4300Mhz effective memory clock

2GB = 900Mhz core clock, 1800Mhz shader clock, 4008Mhz effective memory clock

I just saw this after I made my last post (you posted before I finished my post :p). That's a lot closer to what I'm looking for. Now just another question so I don't have to start a whole new topic and this is somewhat related. If I get the 1gb overclock version can I use it in sli mode with the 2gb even though they have a difference in memory and clocking speeds?

I do realize that having two of the same card is how it works. this is just more of a food-for-thought-type inquisition, theoretical.
