Hi everyone,

My computer is three or so years old and right now its starting to show its strain.

My build is

Case: Cooler Master HAF 912
PSU: Corsair CX600W V2
CPU: Intel Core i5-2500k
Cooler: Corsair A70 (yeaaahh)
GPU: HIS Radeon 6870
MoBo: Gigabyte P67X-UD3-B3
Ram: Patriot G3 8Gb-1333mhz
And a mess of three hard drives

Anyways I was looking on eBay and saw some working Radeon 6870s going for $50-$100 and was wondering if I should crossfire.
My main issue is some lag in some games (which can be fixed by turning the settings down but that's no fun) and most games, like The Crew, use 90%+ of the GPU and heats up the room. So is Crossfire X the solution?
Also I was considering an aftermarket cooler with them but in the future.
 
Well the graphics card will still need more than 1GB of RAM for newer games so I don't think you should crossfire. Even in crossfire you will only have 1GB of video memory to work with and it will bottleneck your extra graphics power.

Get an R9 270x instead. http://www.ebay.com/itm/XFX-AMD-Radeon-R9-270X-R9-270X-CDFR-PCI-Express-x16-2GB-GDDR5-SDRAM-/171646276651?pt=LH_DefaultDomain_0&hash=item27f6ea542b

The R9 270x is almost twice as powerful as your old 6870.

Also here are some benchmarks that will give you a good idea of how much more powerful the R9 270x is than the HD 6870. http://www.ocaholic.ch/modules/smartsection/item.php?itemid=1226&page=4

Thats not a bad idea.

Just curious, what do you say about this: http://www.ebay.com/itm/Sapphire-AMD-Radeon-HD-7990-Dual-GPU-Video-Graphics-Card-7970-R9-280X-/301490415677?pt=LH_DefaultDomain_0&hash=item46323aa83d

kinda caught me off guard.

Or why are 7990's so cheap on ebay??
