Impulsively I went online all of last night and in to the early morning and in a sleepy mindset I pulled the trigger on a BenQ SW2700PT. When I awoke this morning I realized that I'd neglected to consider whether my PC can handle it. My expertise in pixels, not bits and bytes. I don't have a graphics card - I use the onboard Intel® Z77 chipset graphics: Intel HD 4000 on my Ivy Bridge i7 3770K My mobo is the ASUS P8Z77-V PREMIUM From what I've subsequently read the new monitor's increased resolution and resultant complex calculations will tax my CPU. I'm wondering (hoping) that a dedicated GPU will help. I do NOT game or edit video. I do only light netflix viewing but the biggest demands on my system are RAW photo editing. Moving pixels around and displaying it on a high res monitor involves a lot of CPU calculations. Will a GPU help my pc performance? My understanding is that Lightroom 5.7 does not make use of GPU acceleration. A new LR 6.0 version does and this may force an upgrade for me. I was hoping for a complete new rebuild in 2 or 3 years. I hope it isn't required as a result of the new monitor purchase. Any recommendations on the best value (bang for buck) GPU that could help me (and ideally be used in my next build)? I run W10 64 bit, 32 GB RAM, 1 SSD and 2 spin HDs and Antec 620 W PSU. Sincerest thanks for any helpful suggestions!
