Buyers remorse?

Hello,
After doing tons of research, I placed an order for this computer last night. Now I'm concerned it it won't hold up to my expectations. Can any pro out there tell me if these specs will hold up for my needs, which ar primarily t-shirt and advertising design. No video editing. Also, should I have upgraded to higher res screen? Initially I figured I'd get a moniter down the road...but now I'm second guessing myself. Any input would be highly appreciated. I still have a small window left to make any changes. Paid about $1100 before tax.
