In a significant number of experiences, I had 100Mb Cisco switches prove to transfer traffic faster and more reliably than a Netgear gigabit switch. This was replicable time and time again, and I corrected many "mysterious performance issues" by performing what people viewed as a downgrade because a good gigabit switch was outside the budget.
I would almost certainly say you're in for the same experience throwing cheap rubbish at a 10GbE environment. If budget if a concern, buy 2 x 1Gb, quality switches. The result will almost definitely be beter.
