this is my list of the items i am thinking about putting together to build a nice gaming computer. i was just wondering if someone could run a second check for me to make sure i have enough power for everything to run effieciently and that it is all compatible. i am planning on overclocking the i5 2500k to around 3.7-4.0 Ghtz, and im not sure if the fan is strong enough to keep it at a good tempurature. i have a case, so i dont need to worry about that. seeing as im fairly new to building computers, i just mainly needed help with the compatibility and the power comsumption, thanks!
Here we go, it's a little over-budget, but it'll perform much better than the parts you have selected, and will provide a great upgrade path in the future if you so wished.
Generally speaking, you want to get a RELIABLE power supply That Coolmax unit you have selected in your first rig is very cheap and generic, you don't want to risk taking your components out with it when it blows (cheap PSU's are known to do this)
Radeon HD7850 over the GTX280; it's more up to date, uses less power, and has a tremendous OC headroom that can make it perform up to GTX580 levels.
With this kind of budget, you won't be able to OC unless you make some huge compromises, however, the i5 3550 in this list is already a very beast CPU, which can handle any game stock settings
If you have any questions, please let me know and I'll be happy to answer them for you!
