I'm not terribly experienced dealing with the guts of a computer other than changing RAM and just recently upgrading my GPU, so I'm a little lost trying to research a good CPU to upgrade to. So far I've figured out that an i5 or i7 is not an option without also upgrading my motherboard, which I'm not prepared to do at this point due to a limited budget and lack of experience. Baby steps!
My current system specs are as follows:
Windows 7 Home Premium 64-bit
Asus P5K-VM mobo (Socket 775)
BIOS Date: 06/07/07 20:42:24 Ver: 08.00.12
Intel Core 2 Duo CPU E4500 @ 2.20GHz
AMD Radeon HD 6750
6GB of RAM (2x2GB and 2x1GB) (I'm assuming it's DDR2 based on mobo specs)
500w PSU (I don't remember the model offhand)
Running in 1440x900 resolution
I upgraded from an AMD Radeon HD 3850 to my currently listed graphics card thinking that was holding the system back, only to realize I mis-read the recommended requirements for the CPU (Core 2 Duo 2.4GHz for Diablo 3.) The graphics are sharper now but I'm still getting single digit framerates when a lot of physics happens in multiplayer. I also have a sneaking suspicion that the Radeon HD 6750 isn't completely an upgrade from a 3850 although I have no idea in what way.
I'm open to other suggestions, but right now I have my eye on an Intel Q8300 Core 2 Quad Processor (2.5GHz.)
So what I'm wondering is this:
Asus lists a required BIOS of 0902. How does that correspond to the version number 08.00.12? Am I comparing the wrong numbers?
Do I need to consider my PSU wattage for this?
If I'm not planning on overclocking do I need to get a new fan or can I reuse my old one?
Any help would be greatly appreciated.
