Talking about stupid questions drfunk... hahaha
Just install your win7 on that HDD and try, it's big enough. Why would that harddisk not be good enough??
No1 can decide this for you, it depends what you're planning to use it for.
If 80GB is big enough for you, what's the problem?
If you want to upgrade you should look for a nice SSD which I can help you with picking a decent one.
edit; I got a SSD as well, improves your loading times greatly and makes your pc react a lot faster. Great updgrade moneywise. A good SSD will give you more bang for your buck than a better CPU in most cases. Plus you can always instal it in your 'future' new pc. Just buy part for part and in a few months you could upgrade the mainboard/CPU etc.
