Varun044, what are the prices for those parts? Can you give us a run down on prices and where you are buying it from(retailer)? Since its a proper cheap ass gaming build, i would change that H77 board for a H61, that should save you a few dollars. The next bit is that 660ti, if you are paying around 270$ for it, i encourage you to purchase a 7950 instead. http://www.anandtech.com/bench/Product/550?vs=647 Here is a benchmark of both cards in different games, so you can see the difference. If you are buying the 660Ti for around 250-260, please by all means get it! It is a proper card!
The 660Ti is really really close to the 7950 territory for its own good, i love cheap ass builds with tons of graphical juice!
Nothing wrong with sticking to the manufacturer you trust ;) The only change i would make would the be H77, for around 55$ you can get a good H61 board which is plenty for your g630 and 650Ti. I have great experiences with Gigabyte and Asus boards, quality and value if you decide to take a look at H61 boards.
Yes Varun, the USB 3.0 and sata 6 are also available on some H61 boards(they go from about $65-75). If you do want the USB 3.0 and Sata 6, please do look around all the manufacturers you can tolerate as Gigabyte has very few with both 3.0 and sata 6.
