GPU talk looking at new gpu for older system

[Dentash]

Hello been doing some updating this past month and figured I would update my Wife's gaming PC it is a bit dated now but still works fine so figured I would install one of the spare GPU's i have just picking is where i am having the hard part

Her system specs are
ASUS P5Q-WS motherboard
Intel Core 2 Quad Q9400
6Gb Kingston hyperX
OCZ Agility 3 60GB
Seagate 3TB
ASUS HD4850
Windows 7 pro

GPU I have in the house that I have been thinking of using for her setup
PNY Geforce 550TI 1GB
Sapphire RADEON R7 260X OC 2GB

that's the two card i have spare now just don't know what one I want to use in the set up she plays Mechwarrior Online, War Thunder, Elder scrolls online

Id choose Sapphire RADEON R7 260X OC 2GB higher benchmarks than the 550Ti

RADEON R7 260X OC 2GB ranks a 5280 in FutureMark

Geforce 550TI is only 2510

Yeah I have the R7 260x in there now going to install my BF4 on her system and titanfall see how it runs now vs the old HD4850 guess this old 550ti can go in a box and be used as a test card
