Toms is falling into the common trap of 64 bit being all about the ram...http://www.bit-tech.net/bits/2007/ [...] _the_ram/12. Even with less than 4 gb of RAM your 64 bit CPU runs better in a 64 bit environment, your 32 bit applications run better in a 64 bit environment...http://www.sevenforums.com/news/10 [...] fight.html[/citation]
Your sources are flawed:
1 - www.bit-tech.net = Speculation. Its a good article about HOW 64bit should be good, but NO-REAL-WORLD benchmarks. I was at industry tech cons when AMD64 first came out in which software should be running faster. Of course, only LINUX had a 64bit OS that worked for years. MS support for 64bit was years later. (And people think MS is state of the art?)
2- www.sevenforums.com is a forum site in which anyone can post. The display of results is bad with graphics slight too big that EACH one had to be opened to view. The results are badly done, the "test" system is fairly low-end and the author contradicts his own results. IE: He wants 64bit to be "GOD". With a phrase like :
"n every test, except the installation, the 64 bit OS was faster."
His own badly made graphs show otherwise from the rather sparse testing. In two other tests, 32bit OS was faster. And in areas where "64bit WON!" the impressive graphs showing HUGE differences, until you look at the numbers. The funny one is WinRar a Win7 ISO, where 64bit destoryed 32bit... Actual {rough} scores (tester didn't present exact numbers)
64bit OS = 15m 08s
32bit OS = 16m 28s
Everything below 14m 24s is cut out. Like many of the results, the graphs are cut. In another test, the difference is 3seconds for video compression (32bit OS/software WON by 2seconds - one of the test the author forgot that Win7 64bit lost)
Here is a far more professional test with 64bit Vista with 64bit software vs 32bit versions:

Its over a year old and Photoshop has released CS4 since then which has 64bit and quad core support. The test was done on a 4GB rig, which is fair. I don't remember the PRO review I read earler in which 64bit gets FASTER with 6-8GB.
