I am looking for a PC on the higher end of reasonable and the lower end of extreme performance. This PC will be used entirely for gaming and ideally would be able to run graphically demanding games at high/very high/ultra settings at least for the next few years without needing to upgrade.
I had several questions I was hoping the community could answer as well as a spec I would appreciate if anyone could review.
1. I am lead to believe that SLI greatly improves the performance of games by using the dual cards to in tandem to decrease each's respective workload and increase overall FPS and rendering capabilities. The build posted below contains an AMD HD 7950 3G card but was also looking at dual GTX 570 1.2GB cards with an SLI bridge. While there is no doubt that removing one of the cards and running one alone will decrease performance is it THAT noticeable?
2. I was also looking at a single GTX 570 2.5GB card. From what I have read unless I am running multiple monitors or one of excessive size at incredibly high resolutions my benefit from this particular type of card is negligible from the 1.2GB. Is this correct? What about the 7950?
3. In the event that I do not go with either of these forementioned cards I was looking at the GTX 580 3GB as well but worry I may be suffering from the same issue of needless resolutions as the GTX 570 2.5GB card.
4. Will the selected i5 2500k 3.3 GHz processor bottleneck any of these cards too much? I do not plan on overclocking at the moment though I have heard this card is easily and effectively overclocked to speeds of 4.0+. Is this also true?
5. Does the powersupply and cooling system I selected meet the needs of any/all of these builds (provided nothing other than the mentioned video cards changes)?
Spec is as follows:
CAS:Azza Orion Gaming Mid-Tower Case with See-Thru Side Panel [-8] (Black with Red Lightning)
CD:LG UH12LS28K 12X Blu-Ray Player & DVDRW Combo Drive (BLACK COLOR)
