[QUOTE="mm1352000, post: 1093826, member: 82144"] You're probably right about all tuner cards being PCIe 1.0. The thing is that PCIe 1.0 is more than enough for even the most advanced tuner card. A PCIe 1.0 x1 slot is a 250 MB/s bidirectional pipe (= 500 MB/s total bandwidth). Given an average DVB-T 8 MHz multiplex (ie. all channels broadcast on a given frequency) is roughly 2.5 to 3.5 MB/s (20 to 30 Mb/s)... well, PCIe 1.0 is massive overkill, even for a quad tuner card. And PCIe 2.0 is double 1.0. There is zero incentive for tuner manufacturers to use anything more than PCIe 1.0. If Dell are not going to come to the party then I guess you have two choices. Either you take a gamble on a Hauppauge, DigitalNow, TBS or BlackGold card and hope it works... ...or you get a different motherboard. IMO chances of getting a working arrangement are much better with a motherboard from Gigabyte or Asus.
