|Your not going to see much improvment from going from the TL 60 to the TL 68. The price doesn't justify the exta 120+ dollar cost of a 400mhz increase. |
You can't mix an Intel processor with a AMD motherboard if that is what you are asking. They use 2 completely diff motherboard config setups.
Since you have Vista 32bit you can't take advantage of 4gb of ram so upgrading the ram isn't going to help from 2gb to 4gb considering Vista 32bit can only take advantage of 3gb of ram.
The biggest road block for your photo editing is your IGP. it's a Radeon X1200, it's a basic graphics processor and there is no way you can upgrade it because it's intergrated into the motherboard.
You are stuck with what you have. Even if you upgrade the ram to 4gb and throw in 64bit OS and upgrade to a TL-68 your aren't going to see that much improvment then what you have now.
