Froggie - talk to the computer guy that just fixed your computer. They may can put together a new tower for you for very little.
I just got a laptop for Christmas. Got an HP ProBook. We have a computer outfit we use over on the SW side of town, have used them since the early 90s. They put this together according to my DH specs & their recommendations.
I love this thing....DH did a good job.
So, check with the computer guy and see what he recommends.
They have the inside info on whether certain brands and software are good or having problems. And, can make suggestions on getting the best bang for your buck.
Our guy poopoo'd Dell and Acer. Last time he guided us into a Toshiba, but said it's not as good as it once was. Your guy may have a different experience and feelings about it, but he would be the one backing his product....so go with him.
My hubbin builds and works on them as well. He tests most Microsoft apps before available to public even. He has windows 7 and 8. 8 you just have I get used to all the fancy gagits. I still use vista because like y'all I reuse to grow up.
Hubbin also has an works on macs which he hates btw
