I'm trying to throw a new system together that will allow me to run most games coming out in the next couple years on medium to medium-high settings. I don't expect it to handle Microsoft Flight Simulator X on high but I would hope it would be able to manage MMOs like WoW at end-game demand. I don't intend to overclock. The parts I've compiled are as follows:
I'd go for the ASUS P7P55D-E Pro motherboard (ASUS P7P55D-E LX if you do not want CrossFireX or SLI/not going to use more than one card, a SAMSUNG Spinpoint F3 1TB HDD for $5 more (360 GB & faster speed),and this memory kit which has a faster speed and lower latencies for $2 less.
Non taken : i agree if TS was looking for a compiling, rendering or encoding machine ^^ Though i would go 8GB DDR3 non OCZ and if apps dun take advantage of GPU a 880G chipset instead of a HD 5750?
+1^ for you!
Quick edit he did say he wanted to run Microsoft Flight Simulator X on the machine which is more so RAM and CPU Usage which the system I placed together would be perfect at along with the CPU being future proof and the 8GB of Low Voltage memory being future proof as well.
...except for the PSU; the HEC is an old, inefficient design (at best).
I'd take Batuchka's build and maybe bump the CPU to a 955BE.
I run a HEC 1080Watt I just bought from newegg and runs my 2 GTX260 OC Edition, AMD II x 2 @ 3.0Ghz, 4GB Ram, 1TB HDD, Gigabyte gaming motherboard very well and no problems, as well as my old HEC 585Watt.
