I'd also get a good but cheaper PSU, i recommend this Antec
and this Seasonic
PSU's. Both good brands and solid units.
If you're going with a Z68 mobo and a 2100, you'd be wasting a lot of the motherboard capabilities, as those ones are thought to be for the OCer community (meaning you need a 2500k or a 2600k to get the full, true potential from them). I still back up the i3-540 CPU. As you can check on my sig, there are a couple benches comparing this "lowly" CPU to two of Intel's big dogs, and when properly OC'd it keeps up with them, gaming-wise. Plus, 90% of the games are more GPU-dependant, so a better GPU would be a bigger performance boost than a more expensive CPU. Plus, the i3-540 CPU
combo would be cheaper than your i3-2100+Z68 motherboard combo.
Of course, if you plan to future-proof yourself, you can go with the asrock mobo
recommended by anubis1127 and just shell out a bit more for a 2500k
+ aftermarket cooler
For GPU, i recommend a GTX 460
or a 6850
. They both will greatly outperform a GTS 450, and i have them, so i know they will (my SLI 450's work a bit better than a single 460, but a bit worse than a 560 Ti/6850)
8 GB RAM is a nice add-on, and it's not as expensive
, but 4 GB would be OK for gaming.
The whole i3-540 combo with the Antec PSU (shipping is way cheaper than the seasonic) and 6850 (cheaper and better than the GTX 460) will account to $518 shipping included, and that's not discounting $40 from 2 rebates. Hell, you could add the mighty 212 Plus
as a cooler to keep the i3 frosty and it'd be only $26 more. This build is $47 cheaper (plus rebates) and it's better than the previous build you had.Edited by Starbomba - 10/16/11 at 9:41pm
