hey guys i am trying to build a computer that has low power consumption and high performance.
now i these 2 condition's are sometimes considered opposites but i finally came up with this.
1)AMD Phenom™ II X4 Processor 905e (65watt tdp) (pretty strange the 2 less power consuming (45 watt tdp) 605 e and 600e are ranked lower at passmark)
2)ati radeon hd 5770 (think this card could do the job and it consumes 18 watt idle,wich brand should i go for ?)
3)Asus M4A785TD-V EVO (or should i go for the cheapest 790GX like f.e.:Foxconn A7DA-S 3.0 790GX)
4)Samsung HD103SJ(don't think you can save much energy here or should i try looking at a caviar green however at passmark this one outperforms the caviar green (and black) and i don't think the power consumption difference is that big.
5)geil 4gb ddr3 1333 mhz (GV34GB1333C7DC) does more ram make any sense ?not using videoediting etc just normal stuff and gaming
6)corsair450vx (more is overkill or will f.e.: a 650tx handle power consumption better)
7)case:Cooler Master CM 690
major concern:will the processor be any good to handle games like call of duty on high specs ?(not ultra)
4> Green drives use around 20-25% less power. Of course thats 7-8 watts instead of around 10 so its not much compared to the performance loss.
5> 4GB RAM is all most people need.
6> The Corsair 450 will handle a single 5770 easily. It wont hurt to go higher but since you are minizing power consumption you dont need to.
7> You are sacrificing CPU speed to use less power. The Cheaper 125W 955 is substantially faster. You might consider going in the middle and getting the 95W Phenom II x3 720 so you have faster cores, which will perform better in most games than a slower quad. Also the 720 is a BE so you could likely overclock a notch or two without much extra power or heat.
Agreed on RAM, PSU and VGA. CPU is good as it is, but you might also consider a core i5 660. Dual core with HT, good multithread performance and great turbo performance (3.6ghz @ 73w tdp). Not that the phenom isn't good, it's great. Just another possibility.
