MHO is scale the Huge font size down to some thing more normal size. Lite colored text is also a bit harder to read.
Biggest thing is remember in sales you sell the "Sizzle".
Benefits sell not features.
So, spice it up by explaining how wonderful they will feel when they get their hands this hot beast.
Several still pictures up close, well lit to show off its condition.
Tell them what it will do for them.
A short story about how hot it runs,maybe a sob story of why it's on the auction.
Maybe mention what it cost and how much they are saving on the deal?
I know squat about gaming so, you need to come up with the Hot Points to get them drooling over it.
Check out the completed and sold auctions of similar items and do some swipe file work.
NOT rip off but, for ideas.
You ad is far from compelling. It is just a list of features.
What got you hot to buy it? Use those reasons in the ad.
Good luck
