I already own both CPUs and I've already overclocked them both in different systems to the same final speed, so I know that they will both do 3.4-3.6 GHz with no problem.
The E5800 is in my primary desktop PC (the one I'm typing on now), the other CPU is sitting in a box.
The PC in my MAME cabinet is using a E5200 (2MB cache, 800 MHz system bus) currently overclocked to 3.5GHz.
All three chips are Wolfdale core so architecturally, they're the same. The only variables are the cache and the system bus.
The CPU currently in my MAME PC is essentially a slower version of the E5800. The cache and system bus are the same speed and they're both wolfdale core.
What I was thinking about doing was dropping the E7300 into my MAME PC.
The motherboard is a ASUS P5KPL-CM, so it's a tricky board with limited overclocking options, but once you know how it works, it's not a problem. I'm currently using G.SKILL 4GB (2 x 2GB) DDR2 1066 (PC2 8500) memory.
The current CPU in the MAME PC is overclocked using the following settings...
FSB: 280 FSB to Memory divider: 3:5 CPU multiplier: 12.5 Effective memory speed: 467 MHz (DDR2 933 MHz) Effective CPU speed: 3.5GHz
When overclocking the E7300 I'd probably use these settings...
FSB: 333 FSB to Memory divider: 2:3 CPU multiplier: 10.5 Effective memory speed: 500 MHz (DDR2 1000 MHz) Effective CPU speed: 3.5GHz
