It all depends on what kind of connection you have.

LOL! Learn networking plox.
T1 - runs over the copper phone lines; is limited by distance. Max speed: 1.544Mbps Down/Up (all T# are symmetrical (same down/up)). Usual cost is above $200+ (I've only seen starting rates in the $350 range).
Cable - Uses fiber lines for the backhaul (from the central office to a node); node converts fiber (or "light") into electrical signals, carries over coax to 250 - 1000 homes. Because most cable networks are a Hybrid Fiber-Coaxial (HFC) network, distance is not a limiting factor (now, the cable plant may be full and can no longer hold/support more users, so "distance" can be an issue, but not like it is w/ DSL/T1/anything else ran over copper).
For Internet on cable, your cable modem connects to a CMTS (usually at the central office), which normally has 4 download channels (but can have more), and 4 upload (again, can have more). Mbps is 38 PER download channel, and approx. 12-15Mbps on the upload channel...this is DOCSIS 1.x - 2.0. That's 250-1000 homes sharing 4 channels with only 38Mbps down per channel (or 152Mbps total), and the same with upload, but only 12-15Mbps (or 48-60Mbps total).
Oh, and for Comcast, your 20Mbps down, 3Mbps up is with PowerBoost factored in (which is only active for the first 10MB of your download/first 5MB of your upload, and is only present if your down/up channel is empty/can support it during your use); your real connection is 16Mbps down and 2Mbps up (also called "Blast!"), & is DOCSIS 1.x/2.0.

Simple way: You don't know what you're talking about.
edit: To clarify my earlier posts (about me mentioning the 512KB/s & how I ran 117 people off of a 1Mbps line), no matter how much the OP upgrades his PC, he won't see better performance unless his connection speed is upgraded as well (when the time is needed too). =d
