The factory OC's 6950 gets 484 fps in Guru3D's game test suite compared with teh Asus TOP's 495 .... call it a wash ..... but in SLI, the TOP gets 862 fos to the 6950's 759.....that's 103 fps or 14% more and ya save $10 pe rcard to boot. Not to mention, the 900MHz clock "outta the box" easily goes over 1000MHz with the TOP's cooling solution.
And while a 750 is fine for twin 6850's, or 560's ..... I'd use an 850 watter for overclocked versions of either of those GFX cards.....besides PSU's are most efficient at 50% load so no harm in having some headroom, it saves money. Not to mention, it's not about just providing the power, it's about providing stable voltages while doing so and the closer you get to the max power rating, the harder it is for the PSU to deliver that. The more voltage wavers under that load, the harder it is to maintain stable OC's on both the GPU and CPU.
MoBo - Not a bad performer but, personally, I won't support a company that doesn't offer an industry standard 3 year warranty.
Finally the extra headroom will server well as capacitor's age. If ya wanna go with the Strider, it also gets a 9.5 but I'd cut back on the OC a bit.
1) I was tossing up between the 560ti and the 6950. I'll grab the 560ti now, I have seen the reviews and this card does offer the grunt I need. The types of games that I will play with this system are Skyrim, Fallout: New Vegas, GTA5, CS: S & GO and the Mass Effect trilogy. How will they do?
2) Nice catch with the ram.
3) I prefer fully modular psu's for better cable management but I'm leaning towards the psu you chose as it is a better quality one. I knew 850 would be better.
4) I'm trying to keep overclocking to a minimum, if the system can handle most games without lag then that will be great for me. The cpu and gpu will be overclocked as a last resort to achieve that goal.
What 24" monitor will provide the best experience?
Get the 1GB Radeon hd 6950, it won't make that big of a difference. Then later on, buy the second one for a crossfire. If you want to crossfire this 6950, a 750 watt good quality psu is sufficient. get the 850 watts if you feel more comfortable and you don't mind using more money. New cards should be coming in soon, so get a 1 gb radeon hd 6950, use it up then buy a new card to replace it, BUT IF the new cards aren't that great, buy a second radeon hd 6950 for crossfire.
You could also consider that new gtx 560 ti 448 cores. Very nice performance.
the micro-shuttering depends on what games you play I believe. Im going with a 560 ti SLI set up or a 6950 xfire set up myself. There's a controversy on the micro-shuttering issue. Some people say it's worth it, some people say 1 card is better so you do not run into issues at all.
