p45 is a better chipset than an x38. x48 would be close to par with the p45. p45 does not bottleneck the pcie at a substantial (ie "measurable") rate unless you are playing insane resolutions (like 2560 x 1600). there are countless reviews stating this, and a few that still cling to the idea that it does, even at like 1280, lol. as far as the "tables speak for themselves", it aint hard for a website to post up some results favoring whichever board they are in support of. at 1920 i will dispute that ther is as much difference as that website claims. and i'd wager nosboost's left nut (LOL) that there aint NO WAY its 17% faster. it may be a little (and i mean at the most 5-10%) faster SOMETIMES, and that depends on what game, resoluton, scene, etc etc etc the list goes on....
