I can't believe I'm suggesting there might be such a thing as too much upgrading but I'm looking at getting a new PC and don't want to waste money. It's an I7 quad core with 2600 3.4ghz CPU, dual channel 8gb ram, 1TB sata 3 7200 rpm HDD, Intel H67chipset (whatever that means) and USB3 ports (of course lol) I mainly read stuff on here, d/l from vuze etc and transfer lots of stuff to external hard drives for work (and play hehe). I can upgrade to a 2600K unlocked multiplier cpu, p67 or z68 motherboard, 16gb ram, 2 or 3 TB hard drive, wireless network instead of 10/100/1000 gb lan (I don't know what this means either) and either 32 or 64 bit windows 7. Is any of this going to be worth doing, ie make my d/l ing and transferring faster and can someone pls explain what difference it will make between the wireless network or lan and 32 or 64 bit windows? The only games I play are cards and sudoku etc and I don't watch movies or stuff on it. PLEASE HELP ME NOT WASTE MONEY BUT GET AWESOME PC!!
