Somewhat of a noob on this stuff. I recently bought an Alienware X51 I3 with the stock 240 watt PS and GT 545 graphics card.
I just upgraded my monitor to the 27-inch Planar PX2710MW (Killer Price), and now my gaming is suffering. The 545 ran the games on my old 19 - inch at 1366 x 768, but is stuttering a bit in spots at 1920 x 1280.
Based on the power draw, I'm looking at the HD 7750 or 7770 to replace the GT 545.
I want to ask if I'm going to see an appreciable difference if I do upgrade cards. Also, how could I best tweak out the settings to make my games play more smoothly? Presently, I'm play Batman Arkham City, NBA 2K13, and ME3.
the reason why its doing so bad is because cheap gpus arent built for 1920x1280 resolution, let alone 1920x1080 resolution. The higher the resolution, the more its required to pay for a stronger gpu, and a stronger gpu also needs an adequate psu to supply it.
