Planning...no...NEEDING to upgrade my video card. I am running an Asus A7N8X-E dx, with a Barton 2500 OCed to 3200, 1GB RAM, and currently running a slightly OCed FX5600 128MB (dont get nasty, I only payed $60 for it!). With these specs, will I notice the difference between a 9800 and a 6600GT? Is their something more in line with the rest of the system? ATI or NVidia doesn't much matter to me. Thanks.
