Video Card Memory Size

I'm moving into the PCI Express fast lane with a new motherboard and now I'm trying to decide on a video card that is comparable to my current AGP card which is an Hightech Radeon X800 Pro with 256 MB of memory. I've narrowed down my choice to a SAPPHIRE 100116SR Radeon X800XL 512MB 256-bit GDDR3 PCI-Express x16 Video Card - Retail or SAPPHIRE 100105SR Radeon X800XL 256MB 256-bit GDDR3 PCI-Express x16 Video Card - Retail this only difference in them is the amount of memory and price. I have a budget of $400 for my card but I wanted to find out if there would be any benifit to have a card with 512 MB onboard? What do you all think, any ideas or suggestions sure would be great right now....

 

no benefit of 512mb; save the money and buy more onboard memory . The 256mb one has a crappy heatsink/fan combo though. Also look for an OEM package, saves you a few bucks by not including crap you'll never use.

if you get that .. it will still be cheaper than the first one and have a better hsf
