i see video cards have come down in price quite a bit. what is holding me back from having decent graphics? is it more of a CPU or GPU hog? a decent graphics card can be had for about $150. if i did a cpu upgrade, i would also be getting a new motherboard and memory so that would be a bit pricey up front. Would upgrading the video card get me by with decent graphics until i have the funding for the CPU? or should i just wait and do it all at once?
