1. If you want a list of components then u choose definitely i5- over i3 for lot of differences between performance & for some future games. Because in these days some new games needs 4 cores & i3 have just 2 cores. It can't play upcoming games my friend. According to me go with i5-3570k version for best performance & Intel HD 4000 graphics. Yes it is little costly but nothing better than it.
2. Mobo , choose minimum z77 chipset mobo like Asus P8Z77-V LX or GIGABYTE Z77X- D3H minimum for best performance. H61 chipset is very low end mobo. I lost my mobo because it was also a low end chipset mobo. That can't handle new games & crashed.
3. Rams, it's prices r increasing in these days. So go with corsair 2X2gb rams 1600mhz.
4. GPU, go with gtx 650ti boost or ATI 7850. In these days GPUs prices dropping so get a better GPU.
5. PSU, go with corsair or sesonic 500w PSU. It's enough for whole build.
6. Case, you can choose any cheap case at a time then u can upgrade it and also ram too.
7. Wait for haswell for more price dropping of 3rd gen family or go for latest tech.
8. CPU is not playing resolution like 1366X760 , 1600 X 900. It's capability of graphics. Your GPU will decide that on how much resolution it can play. Choose better CPU for loading speed, opening and reading files of anything like games, movies, etc.
I hope it helps.
Thank you.
