I know this is way old technology and I don't want to really bore all of you, but there may be a few guys on here that are familiar with the old AMD stuff and have a moment. Strange or not? I just bought a used Athlon 64 X2 5000 (CU),512Kx2,rev.F2,89W,SocketAM2 and it seems that it is a lot slower feeling than my AMD Athlon 64 4800+ Brisbane, Dual Core, Rev.: G2 Stepping, 0AMD4800IAA5DO - CAAFG - 0818BPNW - W400771E80328. And the 5000 won't overclock any more than 3% without crashing the machine upon boot while the 4800 easily does 10%. I use the required 1301 BIOS on a Asus M2N4-SLI mobo. Not that it matters but I run SLI Mode with 2 8800GT's and the machine does great in games like Black Ops and MW3 (with the 4800) Is it the smaller 512Kb x 2 L2 cache that makes it feel so slow compared to the 1Mb x 2 for the 4800?
