im a newbie to building a PC or buying parts and i have a pretty old machine that has an i3 -2100 at 3 ghz and 2 GB ram and 450 watt PSU so should i buy this card (Zotac Nvidia GTX 650 ti 1 GB DDR5 ) and will it bottleneck on my system ? i just want to play all the recent games at medium settings so the fps is a higher priority as compared to the quality of the graphics also i don't exactly know which motherboard i have it looks like a Intel G series desktop board so please help me with this ASAP !! thank you
