So, I have enough money to finally buy a video card. Anything will be better than this ATI Radeon 9200... So, as I was scrolling around, I found a lot of nice cards with nice speeds. But I noticed 512MB cards have DDR2 speeds...but there are GDDR3 512Mb card, but they're over or about $200...I'm trying to keep the price from $150 to $170. And many of the 256MB cards are GDDR3 and are about the same price as 512MB ddr2 cards... The question is, should I pick the ones that have more memory with less speed, or the speedy ones with less memory?
