There is no point going i7 with a single 4870 for gaming. I personally would put the 4870s in the phenom systems and use phenom II x3s instead. For the i7 builds I would use a core i5 instead and use a 5850 or a 4870x2. This graphics power is especially necessary for 1080p monitors. I would also use 5x 700W power supplies and 10x500W PSUs. To be safe.

Thank you Enzo Matrix for your reply, i guess the reason i am going with i7 with running single 4870's is in hope that it will be good enough for today's standards; an upgrade in video cards in the next 6 months would be due. Unfortunately the budget is already stretched out as far as i can really take it personally, that is untill the Digi bean begins to revenue some profits for expansions.
I chose i7 as a base with a lower end video card to conserve budget and to keep options open for future upgrades.
Corect me if im wrong but if i stacked 15 dual cores, in the upcoming years when developpers make full use of all cores available would i not be kicking myself for not going with a good mobo/quad processors to start?
Yes your design would be dependant on how long you plan to keep the computers.
A single 4870 is good enough for todays standards.
And yes I would definitely not go with a dual core cpu for even today's gaming.
The i7 is the best performing cpu today, you could probably keep that for a while. The AMD systems are good too because they tend to like to keep backward compatibility with their sockets. It's entirely possible that their next CPU line would work on AM3 sockets. My suggestion of a phenom IIx3 is based on that the phenom II outperforms the older phenom design. If you want to go quad core at that price, the Athlon IIx4 would perform better than the old phenom because it is based on the phenom II, just without the L3 cache (who's performance benefit is debatable). Not to mention the Athlon II x4 620 is clocker higher at 2.6GHz
The 9500gt would not really make a game like call of duty 4 playable on maximum settings at 1920*1080. I would go the extra mile for the 9600gt. Use the money saved by going to an Athlon II x4.
If you want go go for longevity, your money would be better invested in Windows 7 64-bit. 64-bit right now is between "the future" and "the now". But closer to "the now". Windows 32-bit will not recognize more than about 3.5GB of ram, so it would definitely not be good when it is time for ram upgrades.
I would also recommend going with an AM3 board that supports DDR3 ram for your AMD systems. The ram will be about the same in price, the motherboard might cost a touch more. Here is a good one that also supports crossfire, if you ever want to do that with two ATI cards.

To give me a better idea, what games will be played on these computers? Also, is overclocking or tweaking these systems in the future an option?
