Core 2 Duo 2.66 GHz
Nvidia 8800 GT 512 MB
6 GB DDR2 800 RAM
EVGA 680i SLI MB
Monitor - 1680 x 1050 (max likely ever 1920 x 11200)
I use this computer for simulator games only (in particular FSX and DCS Blackshark are the only ones loaded). I am able to play these with decent frame rates on moderate high details (30 fps+) but I would like to get above 40 fps with the eye candy really dialed up.
I am not a typical overclocker though I could probably be favorable to something that was easy to overclock (multiplier on the Phenom II or the turbo mode on the 1156 i5/i7 systems)
I have been doing ALOT of reading and there seems to be numerous spins on many themes. Some of the things I have read are
-Memory speed/rate doesn't have a significant real world impact on game performance (i.e. I am about as well off with 6 GB of 800 DDR2 as I am with 6 GB of 1600 DDR3)
-Games for the most part use 2 cores max and that a fast core 2 performs as well or nearly as well as an i7 in these applications
-Top end cards now can only really take advantage of an x8 bandwith on an SLI so there is no harm in having x8/x8 vs x16/x16
Leting things play around in my head I have been working through some scenarios, 3 of which ditch all of the performance components and a couple that salvage part of my existing system. I have made it a personal goal to keep the investment below $800
When I did this order, I didn't take value and best bang for buck into consideration, I just took into consideration the gaming potential.
As for your myths:
1. Memory: I would personally agree with that but I have nothing to back that up.
2. Dual core: It used to be this way but games are now starting to work better using more cores. Last I checked modern games showed little performance difference between x3 and x4 but x2 to x3 shows a gain. In the near future though, games will be more multi-core optimized.
3. PCI-e bandwidth: I'm not sure.
