Is a Core 2 Duo E8400 @3.00 GHz ready for ARMA 3?
I wish I could overlcock my cpu, but my motherboard is from Dell which means the bios is locked, limiting me to stock speeds. I really don't want to downgrade to a previous generation cpu, I would like to stick with my 45nm architecture, 6mb L2 cache, 65w tdp, and 1333 fsb.
Then what I'd probably do is get a Yorkfield (basically two 45nm Wolfdale dies on a single substrate, just like the older Kentsfield was a pair of 65nm Conroe dies) like a Q8200 for example but that is 2.33GHz and 4MB L2 cache, there is also a Q8400 which is 2.66GHz.
Also the Q6600 is an older gen but I'd imagine it'll perform better than the dual core, you still have two extra cores and an extra 2MB L2 cache
I've just found a Core 2 Quad Q9500 which has 6MB L2 cache and 2.83GHz but I have no idea on the cost, also no idea whether it's actually worth doing but if I was sensible then I'd probably just use it as it is for a while and save up for a more modern machine, even if it's a 1st generation Core i series, those are still good CPU's but if you want to keep the 65w TDP then you could have a look at an E8600 which is your CPU but clocked at 3.33GHz.
If you could find one pretty cheap then you could consider the Q9650, 3.0GHz and 12MB L2 cache but once again I have no idea on the price of those and because it's pretty old hardware now I'd imagine they are quite expensive, especially the higher end chips.
