hi there
Your processor is fine, it's still a dualcore so it's not that old, your motherboard has a 16x PCI so the slot for the graphics card is right. The 7750 card doesn't use massive amounts of power but my main worry for your set-up would be your 180W PSU.
i ran your old system with the GT610 through the extreme power supply calculator and it was right at the limit (saying 182 watts necessary and recommending 232watts) with the 7750 card it gives 200w minimum and 250w recommended.
so, all in all, i would say keep everything else and maybe consider a new power supply - I'm not an expert so i'd be interested in hearing other comments on your set-up
good luck it's a great videocard for the price and the 2 core duo still holds its own.
Thanks For the reply
Will HD 6570 be fine in place of HD 7750?
to be honest i think the 7750 is a much better card and the power usage is only a few watts higher with the 7750. The price difference shouldn't be that great so my response would be no, don't go with the 6570. either go with the 7750 and invest in a cheap Power supply or keep the computer as it is. Keep in mind that there are some good PSU's out there at 450/500w at relatively low prices.
to give you better feedback: can you tell me why you want to upgrade? what games do you play or what graphics programs are you using?what resolution is your screen?
