Hello, this might be embarrassing but the last time I did a CPU upgrade was a shift from an Intel Pentium 4 2.8 to and Intel Pentium D 2.8. I'm trying to upgrade my system now that I've graduated and I'm really confused about which of the 2 CPUs is the better choice. There seems to be not a lot of review for the 925 so here I came and decided the community instead. Thank you!
Since this will be an all-new build, you may want to use the sticky on asking for new build advice. Your answers to the questions in the template will help us help you build a nice machine, whatever your budget.
Thank you for the inputs. And the chart was really helpful. I was hesitant to post on the new build forum since it's just the CPU that I haven't decided on yet. It seems to me (but I'm not sure since I'm new to the site) that Athlon 640 is better than Phenom 925, but Phenom costs more. Kind of confusing.
I do have an HEC Power 480 now, will that be enough if I'll the Phenom with 5770 Vapor-X?
Theoritically, a 480W PSU should be enough for an overclocked Phenom II and a single HD 5770.. Practically however, it depends on the technical specifications of the PSU.. HEC is an unknown brand for me so its quite natural for me to recommend you to stay away from it and get a PSU from one of the known brands (like Corsair, Seasonic, Antec) instead..
I think I'll be getting the Phenom. Unfortunately, those PSU brands are quite hard to find at least from where I live so there's not much of a choice there. By the way, this might be off topic but with my choices being Phenom + 5770, how much power do you guys think those two would consume?
Considering a highly overclocked Phenom, an overclocked HD 5770 along with the rest of the standard components, a good 450W PSU will be enough.. Consider getting a 550W unit for extra headroom and/or any video card addition(s) or upgrades in the future..
With an older HEC, that's a claimed 33A. Even if the reality is more like 26-28, it ought to still be enough though. When considering a replacement PSU, look for one that has full range active PFC (no little voltage switch) and 80+ certification. 80+ tests under unrealistically cool conditions, but at least the unit could output 100% of its claimed rating for a decent period of time (so it was warmed up some), and did it efficiently. Higher temperature would affect those, but most likely efficiency first. Antec, Seasonic, Corsair, Enermax, XFX, some FSP, a few (only the latest) Coolermaster, and the latest NZXT should be decent.
I just saw the prices on GTX 460 768MB dropped and I'm considering it now (though it requires 2 6-pin PCI-e power connectors). Also, I saw an abundant supply of Phenom 945 in a local store here which I'm also considering. I know most of you recommended to get a more decent PSU but I'm really on a budget. So with a Phenom 945 and GTX 460, would my PSU cut it?
