Michael King7 said:True, but I'm running DDR2 RAM. I didn't realize a GDDR5 graphics card could work on a DDR2 motherboard. If that's the case, why wouldn't I just buy a more powerful card instead??
I'd spend my max $233 on a card with 2GB, but if not, then 1GB
And I'd definitely be looking for something new
Like I already told you, the video memory on your graphics card has absolutely nothing to do with whatever RAM you have on your motherboard. You can go ahead and grab a GDDR5 card without any issues.
Regarding the capacity—you won't notice much difference between 1GB and 2GB at resolutions up to 1920x1080, but you *will* feel the difference between DDR3 and GDDR5. It makes way more sense to pick up a 1GB GDDR5 card for a tiny bit extra cash than to settle for a 2GB DDR3 card just to save a few bucks.
Higher-end cards come with 2GB standard, which is expected, but in that $600-$233 range, it doesn't make sense for you, nor do you actually need it for those lower-tier setups. crimsonstag84 linked you a good option above, or maybe this one—though they were out of the 7750 last week (and many others too). They're slowly disappearing unless they've restocked... and by the way, I hope you're at least running a decent dual-core processor.
