A friend still has a socket 939 mobo and does not want to upgrade untill the X48's come out...
So he wants to buy a CPU.
Which one would be a better buy? He can get the 170 for about 20 bucks more then the 4200+ so the price does not matter to him.
He is pretty much a gamer, so that is all he plans on doing with the system. He is getting it to get a boost in WoW FPS. His current CPU is the 3500+ and it gets hit pretty bad when he is in a large raid and running some plugins.
Which one would you suggest for gaming? The mobo he is using is the GA-K8NXP-SLI.
I told him to just get the cheaper one (4200+) since its clocked higher... But it does have less cache.
A 4200+ should be good for a small overclock no matter what, but the Opterons are overclocking beasts. The L2 Cache difference depends on the apps you are going to be using it for, but is going to overall be relatively small.
I have been messing aroudn with my X2 4200+ and I got it to overclock to 2.64GHz very easily. I just looked at an Anandtech article on the CPU and used the voltage they used and what not, and no problems at all.
One issue is that the 4200+ will not come with a Heat Sink and Fan, the Opteron 170 will. So if he doesn't want to buy a new HSF, than get the Opteron. Either way he'll get a performance boost. ALSO!!! Make sure you download the Dual Core Optimizer. Very important.
