So I went to the ***New build guide*** link, and decided to try building the $500 range comp (Its my first time and i need somewhat hand expierience with computers) I was looking at the video card the guy somewhat suggests (HD 4670) and in newegg i noticed the Ram type under specification. It says GDDR3. However in the ***new build guide***, it says to buy DDR2. Do i need to get the newer type, GDDR3 or will it still run with DDR2 ram?
