no, you need to spend $80 bucks so you know what digital viberance, gamma and seeing colors out of the 16bit range. your lack of a good card is whats making your skins look bad. while they may look awesoem to you, the rest of who are on higher end cards see every little pixel and flaw in these skins your posting.
like no offense but im running a 8800. when i see your hog skins in game i can literally see where your brush stokes are and where you have gone out the detail lines. your card prolly is capable of rendering that high quality in photoshop for you to notice it and automatically creates a "blur" effect for you.
in essence, what looks good on your photoshop will look way different in mine and in others.
thats why you need a better card. you want to do graphics work, then get the right tools. just having photoshop isnt going to cut it. your going to have to see what your working with in great detail and render your work with the most colors and viberance aviable. clearly your card isnt capable of doing that. thats why your skins may look good to you and not to others.
either that or your have really poor taste in what looks good and what doesnt. thats your call.
