Now I was wondering if there is an archive or way to access this kind of info when you want to look at the performance comparisons for the type of hardware you are looking at
From the main page, go back thru the reviews and features. MPC has a couple of good Video card round up reviews that does some pretty good comparisons.
Also look at some sites like Anand Tech, Benchmark Reviews, Guru3D, Hardware Secrets, jonnyGURU, etc. They all present the data from several relevant cards along with the one they are reviewing for comparison. Some good examples would be:http://www.anandtech.com/show/3987/amds-radeon-6870-6850-renewing-competition-in-the-midrange-market/1http://benchmarkreviews.com/index.php?option=com_content&task=view&id=628&Itemid=72http://www.maximumpc.com/article/features/sli_vs_crossfire_which_dual-card_setup_besthttp://www.bit-tech.net/hardware/2010/03/27/nvidia-geforce-gtx-480-1-5gb-review/1
This forum should be fine at this point to discuss the pros and cons of the various brands and power of the cards. But the Help Me Buy forum would be more appropriate for help matching up to a system/monitor and the uses you will be putting it to.
