You don't get my point.
I said there is little sense in buying a 5.5K motherboard for a 3.5K processor. Instead, either get a 2.5K board or use the extra cash to either get a better CPU (which I don't recommend seeing that E5200 is THE most VFM CPU ever) or just save the cash for a later GPU upgrade perhaps. E5200 also supports SSE4 btw.
G31 is NOT like 945GC. It has energy saving capabilities and also has enough expansion slots for a simple setup upgrade later in the future. All i30 series and i40 series chipsets, including the most basic ones like G31 are highly mature and stable and ALL of them are great overclockers, and though obviously the higher end ones are the best for overclocking, you will get a better overclock (according to some reviews) if you invest the 3K saved on a basic water cooling solution or a high end air cooling solution.
And btw, G41 is the successor of G31. Try to see if its available for under 3K. If yes, GRAB it and stick to it. It has much better onboard graphics and overclocks much better.
2) M.B ---- ASUS p5VM SE= 3300 Rs (965 chipset wd 8GB RAM support)
Won't do. 965 does not support current generation Core2 CPUs. Its too old a chipset to consider.
And yeah, looking for over 4GB ram IS silly, considering that Windows 7 uses less RAM than Windows Vista due to which the configurations you may need in the next 4 years (windows 7's minimum life cycle) would be able to comfortably run with even 2GB RAM.
By the time you decide to upgrade, the following things will be seen:
1. DDR2 would be a lot more expensive because DDR3 would be mainstream.
2. It would be cheaper to sell off your old rig as spare parts than buy expensive old-hardware upgrades for it.
e5200 ocs well to 3.45ghz on g31. Higher is not stable most of the time. Using better chipset like p35/p43/p45 would also require a better aftermarket cooler for further ocing.
even 3.4GHz for E5200 would make it VERY powerful and enable it to compete with higher end E8xxx series CPUs in gaming.
