Hi. I'm looking to update my pc. My current pc specs is CPU - i3 3220 , GPU - GT620 OEM 2gb , RAM - 4gb DDR3 , Motherboard - DB75EN. I'm wanting to upgrade my GPU to a GTX 750 1GB and also my RAM from 4gb to 8gb. I wanted to know how my computer will perform. I play games like battlefield , F1 , Planetside 2. And also i do 3D modeling in Autodesk Inventor pro 2014. I don't make big assemblies but only upto maybe 20 parts. I wanted to know how my pc would perform in the above mentioned tasks and would my CPU bottleneck my GPU. P.S. I have a diplay of resolution 1440 X 900. Thanks!
