Ive thumbed through these boards as well as others and have not been able to find a real answer to this question.
What is the performance increase from PCIe 16x 2.0 verses 1.0? Is it worth buying a newer mobo with 2.0 and buying a new 2.0 card?
Right now i am using an old system i build back in 1999 with RDRAM and am seriously needing to build a new one. The above question as well as trying to figure out if i should go ddr3 or not are my only real issues. As far as budget goes i would be looking about about $1200-$1500 for the whole system not including display and mouse/keyboard.
the main difference between pcie 1.0 and 2.0 is bandwidth. 2.o has double of it. but it's only maximum bandwitdth. it doesn't mean that a card will actually use all of it. it's mostly a feature for future graphics cards. i's worth buying one for future upgrades. also the 2.o can supply more watts for the gpu. that means some cards might not have to have two 6pin plugs, one might be enough.
stick with ddr2 it's much cheaper plus it's only slightly slower than ddr3. simply overclock the ddr2.
Too add to what everyone else has said I believe that PCIe 2.0 also has power saving features built into it. I am guessing here is that its sort of like Intel's speed step thing in that when running your video card in 2D mode it can cut the amount of voltage to the video card and when it needs more it can take more.
Of course my brain is tired and this could all be a hallucination on my part, If it is please have mercy on me lol
As far as my 1999 rig. Thats going to be a media whore. I just going to stick all my mp3s and movied on that and share it through out the house. I will be building a new rig for gaming. Right now im still useing the 1999 for gaming, it works for mmorpgs alright on medium low settings untill something exciting happens then the fps drops to about 5-10 lol.
Thanks for the input, im going to go with pcie 1.0 and ddr2 for now. When the need for 2.0 arrives and ddr3 show better performance for the buck ill build another one.
lol, you did nothing wrong, it's just that I noticed that "new build threads" gets much more attention than the current thread was getting. I suggested a new thread just so you would get more reviewers and comments.
