1) I have a few servers laying around I know they don't have a decent GPU due to onboard graphics but is running duel quad core Xeon processers could they me used for mining?
Could they? Yes. Should they? Hell, no. Don't even dream about CPU mining if you hope to make a profit.
2) due to GPU mining becoming more difficult is it worth mining at all?
Not unless you have extremely cheap electricity and/or an ASIC/FPGA.
3) kinda apon the last question. Due to this time of age of bitcoin is it worth spending the money and time investing in mining bitcoins?
Who knows. It is impossible to predict future difficulty or future prices, so what's profitable now might not be profitable in a few months (and vice versa). As with any investment, there are risks involved.
Kinda also come to think about It this is kinda a good boobies guide for someone who wants to start off.
I recommend
