Curious whether anyone had the ultimate experience with FSX on 8-core CPU systems?I was considering a Mac Pro as a replacement for the last remaining PC at home, and today Apple posted their new 8-core system with quite acceptable price tag and a variety of GPU options including 8800 GT (DX10 compatible?). so I was wondering if 8 cores is really a significant improvement over, say, 4 cores and how good Windows XP or Vista handle it?Cheers,=S.V.=eMachines T5026/P4/3.07GHz/1Gb RAM/160Gb S-ATA HDD/Windows XP Home SP2/ATI RADEON 9250 PCI 256Mb/ViewSonic VX910 19' 1280x1024/Microsoft SideWinder Force Feedback 2

There were major problems. I'd stay way clear.

It was an FSX problem or possibly a BIOS issue.

When was that test run?(Curious if it was post-SP1/SP2, when better multicore was introduced)-Greg

It was post SP1.QUAD COREMotherboard - Supermicro SATA Bsckplane, X7DAEProcessors - 2 x Intel Dual Core Xeon [email protected] Cores - 4RAM - 2 GB ATP Fully buffered DDR2 667 FB1024-8A667Display - Saphire ATI RAdeon X1950 ProHard Drives - 6 x Seagate SATA II RAID 0Case - Supermicro SC743T-650WDOUBLE QUAD COREMotherboard - Supermicro SATA Bsckplane, X7DA3+Processors - 2 x Intel Quad Core Xeon [email protected] Cores - 8RAM - 4 GB Kingston Fully buffered DDR2 667Display - XFX GeForce 8800 640MB XXX EditionHard Drives -Seagate SATA IICase - Supermicro SC743TQ-650WVerdict 40FPS continuous settings on high on the quad core setup @ 1920x1440x3222-23 FPS on the double quad core setup at the same resoultion and settings as the quad.Both machines were clean builds with most recent drivers at the time of the build.

Benchmarks show here is little to no gain in FPS by adding more cores.
