With the Intel Core i3-540 costing roughly $105, it can be a great processor for a solid gaming build. This processor beats out the Athlon II X3 445. If you want a higher clock rate for about $15 dollars more, then I would suggest going with the Intel core i3 – 550.
The GeForce GTS 450 graphics card comes in at around $120, and is by far a great card for its price range. You should get a great performance of 16 80×1050 resolution in most games, and 1920×1200 with lower game details. (If you want to get a slightly better graphics cards for a slightly slightly higher prices, consider the other cards in the “Budget Yielding Alternatives” section below)
