This thread is interesting and my response is the same to the people that say don't get 1 GB or 2GB of system memory because this is a waste. If some of this was already said in this thread, then I apologize but here's my opinion on this matter. There are two main points to this argument: cost and upgrading frequency. The cost for these boards is kinda high right now and I wouldn't get one now, but that shouldn't stop the people that can afford it to get one. If you upgrade a lot, then it may seem like it's not worth it and you're probably right; but for the people that hardly ever upgrade or do a massive upgrade every 2-5 years, then it might be worth it. I plan on getting a Radeon 9800Pro 256MB for my new system build in about 4 months.
As far as games, there have been some valid points regarding AA and AF, resolutions, dual monitors and stuff. For anyone that plays UT2003 custom maps, 256MB of video RAM and 1GB of system RAM can help a lot. Ever play the map DM-2019? It requires 640MB of system RAM to run. I'm sure the more video RAM the better for this map. Of course, this is only one map, so take that as you will. Also, as far as the future, I'm sure there are a lot of people saving their money for that first PCI Express video card, hehe.
Holy carp! Is UT2003 a year old already?!
