Help with upgrading old computer please

You better buy a HD 7770 $120-$150. And the problem with your current specs is the CPU. Your CPU will bottleneck a fast gpu. If you can upgrade it to any core 2 quad. Any used core 2 quad will come really cheap.

How much would they cost used ? And will it work with my motherboard? I am new to upgrading comp parts

You should be fine with your current cpu for gaming. You could easily overclock it to get more performance also.

The processor is discontinued but you can get a used processor that should cost around $50-$90

http://www.ebay.com/itm/Intel-Core-2-Quad-Q9300-2-5-GHz... $75

http://www.ebay.com/itm/INTEL-CONFIDENTIAL-CORE-2-QUAD-... $110

http://www.ebay.com/itm/Intel-BX80580Q8300-SLGUR-Core2-... $135 Best offer since it is a new one.

If you are going for the used processors I recommend calling the sellers first and get the quality of the device reassured.

Although all the processors should be compatible with your board I'd recommend you check the CPU support list on the motherboard's webpage.

Looking to add to a old system and want to know if my CPU will get bottlenecked by my GPU (the one i buy) and that i will be able to play games on med/high with at least 30FPS. Specs for my computer now below, specs in brackets what i plan to buy.

Pentium Dual-Core CPU E5800 3.20GHz

4GB Ram

1 TB hard drive

ATI Radeon HD 5450 ( either the ASUS AMD Radeon HD 6670 1GB GDDR5 or the GIGABYTE GeForce GT 640 OC 2GB GDDR3 )

300w PSU

Asus P5G41T-M LX2/GB motherboard

any help appreciated and remember i cant build a new system has to be a upgrade and sorry if in wrong category.

Although the GT 640 has 2GB, I´d definitively go with the HD 6670 -- the GPU might not bottleneck the CPU.

It would help if you place another 4GB ram, tough DDR2 is quite expensive, and hard to find.

So if i went out and bought the HD 6670 i would be able to play my games like borderlands two on med/high with decent FPS ?

^ Would depend on the resolution your running at.
If its 1080p then no way are you getting med/high settings, 720p then probably yes on the medium settings. Below that then its likely you could get med/high.

I may need to get a new monitor as-well, its a weird one, the resolution is 1366 x 768

So roughly 720p.

Ok cheers, do you reckon that i should upgrade my CPU first of get a new GPU first ?

Upgrading the CPU in any meaningful way will result in a whole new computer (new mobo needs DDR3 RAM and a new OS, need a SATA HDD, it goes on).
Would stick with just the GPU upgrade.

If you still want better performance, you would need to get a whole new rig.

Ok cheers for all your help, hopefully if i get the 6670 i should be able to play on mid. Cheers
