What is the best Single Case slot GPU? Problem!

[ICSFan]

HI   

Ok So I have this HP desktop that its due for a graphics card upgrade ( PSU as well)

So far I am running a 365W PSU and a XFX Geforce GT 240 and it runs ok for games but definaltly time for a better card.

See, as in this picture here,

My motherboard ( in a sense) is upside down, and my PCI X16 is facing upwards, making it so all my cards face up. Therefore,
Limiting me to a single slot card. ( see pic above)

I was pretty mad when I got the machine, realizing this problem.   

What are some ideas that I could do? Is there any gaming cards that only take the one slot? ( as seen in picture)?

Im stuck and I dont know what to do

What do you mean the MBoard is upside down ? ?

Most vid cards are single slot design...more info on the actual PC and what MBoard is gonna determine what vid card it will take...
