Advice on new Budget Receiver

I have found a Denon AVR-1713 on sale for a good price (I don't think we are supposed to post pricing here). My old receiver is probably over 10 years old, and starting to act up a bit. My setup is a frankenstien matchup of random componants

I run all my HDMI inputs (shaw portal, xbox360, Aios media box) to the tv (60" Sharp Aquos), then an optical audio from the tv to my Receiver (Teac AG-D9100).

Matched with the receiver is a couple massive Pioneer CS-G404 fronts, Pioneer HTP300-CR Center+Surrounds (10+ years old), and a Velodyne VDR-12 (1 year old). And to my untrained ears, this setup sounds pretty good with the exception that I have to crank the center channel to hear dialogue.

The wife is spending most of the budget on furniture, so I won't be replaceing my speakers right away. But I was looking for input on the AVR-1713. The setup is typically used 40% TV programing/series, 40% movies, and 20% gaming.

If you have any input about this receiver, and if its a decent step up from my Teac relic, any comments would be appreciated.

Thanks in advance.

Addendum: my viewing area is aprox 14'x14', but one side is completely open to the kitchen (no partial wall, so technically it extends another 16' off to one side.

Indeed, these are 3 way boxes with a large (16" looks right) woofer. They aren't the prettiest thing, but still sound good. I bought them as well as the center/surrounds at costco back when I was in university. I may even build a cabinet/tv stand and incorporate them into the design so they are 1 large piece. I ended up ordering the Denon, and can always take it back if it just doesn't sound good, but I'd have a hard time believing it wouldn't outperform my old receiver.

The Sharp is quite nice. I bought top of the line about 5 years ago on a 37" sharp ($3200), and saw how prices plumeted. So when I bought my 60", I refused to go for the best, and just looked for good reviews. I think this one was $1100 1 year ago, and many comment on how good the picture looks, even with a Shaw Cable HD source. It's not a fancy 5mm thick model with no bezel, but I'm still happy with it for what I paid for it. Also note that electronic prices in Canada are much higher than the States.
