I'd give it 4 out of 5 star rating, if you could possibly get an i3 or greater instead of the Pentium G620.

To answer your question, yes the G620 is compatible with LGA1155 motherboards.

You need a dedicated graphics card to play most games (except Runescape maybe). Any modern PCIe graphics card will work with your setup, just depends on your budget...

Anyways Depending The Budget I Need a good Gfx Card which wont be Any Bottleneck to the Pc suggest any for the 70-120$ budget

Actually for the games you play you can get a decent card for $120. For example purposes here is one: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125410

I also agree with cliffordcooley about an i3 over Pentium G620. For comparison sake: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007671 600095610 600005584&IsNodeId=1&name=Core i3

By the way, who do you main on League?
