How does this computer build sound?

I'm shopping around Newegg to try and build someone a PC - however I've only built three PCs in the past and was wondering if this is a decent build for gaming.



MSI 870A-G54 Motherboard

ASUS ENGTX550 TI DC TOP/DI/1GD5 GeForce GTX 550 Ti (Fermi) 1GB 192-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card

AMD Phenom II X6 1045T Thuban 2.7GHz Socket AM3 95W Six-Core

I plan on getting a 700w power supply and about 8 gigs of RAM, as well. He hasn't told me what size HDD he wants and sound card and CD/DVD burner will probably be something cheap.How does this computer build sound?
You'd be better off with a faster AMD quad such as the 955/965 BE for around the same price. The 550 GTX Ti is kind of crappy. I'd go 560 GTX/GTX Ti or better



You do not need a 700 watt PSU for that buildHow does this computer build sound?
