Hey guys, I need to know what's the best graphics card that fits in a mini tower. I have a Dell Inspiron 530 (NOT slimline) with Intel Pentium Dual Core E5200 2.5GHz, a 600W PSU, 4GB RAM, a 720G HDD and an Intel Integrated X3500 GPU. Before I had the problem of a cramped PSU but I have that fixed. I usually game at mixed settings (mostly low-mid) at 1280x1024 res. Any help?
