Need help upgrading a graphics card in an old computer Tags: Graphics Cards Computer Radeon Graphics Last response: April 2, 2010 4:37 PM in Graphics & Displays Share creamsoda April 2, 2010 2:45:48 PM Hey everyone, I'm trying to upgrade an older computer for my son, but am unsure how much to spend on a graphics card, because I don't know how much the rest of the system will bottleneck performance. Here's what's there now: Thermaltake 430W PSU AMD Athlon 64 3800+ CPU 2 GB PC 3200 DDR SDRAM GeForce 6600 GPU Windows XP I'm think about one of these cards (after reading the latest Tom's rankings): Radeon 4650 Radeon 4670 Radeon 4850 GeForce 9800GT Questions: How much performance boost will I see with each of these cards? Which cards will be bottlenecked? Thanks for the help!

If you are unsure, take a look here: http://www.playtool.com/pages/vidslots/slots.html | Report abuse creamsoda April 2, 2010 3:38:41 PM It's got a PCIe slot. The current 6600 is a PCIe. So anything above a 4650 to 4670 is a waste of GPU then? Should I go with 512 or 1 GB? Also, how much boost am I going to see going from the GeForce 6600 to a Radeon 4650 or 4670? | Report abuse shadow187 Graphics card Master April 2, 2010 4:25:00 PM You'll see more than a 100% boost probably. Grab an HD4670, and a 512Mb version. | Report abuse coozie7 Graphics card Master April 2, 2010 4:37:01 PM There is not huge difference in prices between the two TBH, so yes, grab a cheap HD4670, but do not be afraid of the 1Gb cards, that said, do not pay more for a 1Gb card either, the HD4670 is just not fast enough to use all that memory. | Report abuse Register or log in to remove Ask the community Publish Tom's Hardware>Forum>Graphics & Displays>Need help upgrading a graphics card in an old computer> Related ressources: ForumUpgrading old graphics card - need suggestions ForumNeed help upgrading my old computer ?
